Subject: [PATCH 001/658] feat(hooks): add block-image-read hook to prevent
 context overflow

Add PreToolUse hook that intercepts Read tool calls on image files
(.png, .jpg, .webp, etc.) and blocks them with helpful message.

This prevents context exhaustion when image generation skills
produce multiple files and the agent tries to read them (each
image can consume 100K+ tokens).

Configuration:
- Enable via config.yaml: hooks.block_image_read.enabled: true
- Or env var: CCS_BLOCK_IMAGE_READ=1

Hook integration:
- lib/hooks/block-image-read.cjs - the hook script
- src/utils/hooks/image-read-block-hook-env.ts - config loader
- Integrated into all spawn locations (ccs.ts, shell-executor,
  cliproxy-executor)

Closes #426

+ * CCS Image Read Blocking Hook
+ *
+ * Blocks Claude's Read tool from reading image files to prevent context overflow.
+ * Each image can consume 100K+ tokens, causing immediate context exhaustion.
+ *
+ * This is a PreToolUse hook that runs BEFORE the tool is executed.
+ *
+ * Usage:
+ *   Configured in ~/.claude/settings.json:
+ *   {
+ *     "hooks": {
+ *       "PreToolUse": [{
+ *         "matcher": "Read",
+ *         "hooks": [{
+ *           "type": "command",
+ *           "command": "node ~/.ccs/hooks/block-image-read.cjs",
+ *           "timeout": 5
+ *         }]
+ *       }]
+ *     }
+ *   }
+ *
+ * Environment Variables:
+ *   CCS_BLOCK_IMAGE_READ=1       - Enable blocking (required)
+ *   CCS_BLOCK_IMAGE_READ=0       - Disable blocking (allow all reads)
+ *   CCS_DEBUG=1                  - Enable debug output
+ *
+ * Exit codes:
+ *   0 - Allow tool (pass-through)
+ *   2 - Block tool (deny with message)
+ *

Subject: [PATCH 002/658] fix(hooks): enable image-read blocking by default for
 third-party profiles

Match WebSearch hook pattern:
- ENABLED by default for settings/cliproxy profiles
- DISABLED for native Claude accounts (account/default)
- User can override via config: hooks.block_image_read.enabled: false

This ensures CCS CLI users get context protection out-of-the-box
while native Claude subscription users are unaffected.

Subject: [PATCH 011/658] fix(delegation): dynamic model display from settings

- Read ANTHROPIC_MODEL from profile settings instead of hardcoding
- Display model name in full uppercase (GLM-4.7, not Glm-4.7)
- Add null/undefined guard to getModelDisplayName
- Remove hardcoded GLM-4.6/GLM-4.6 (Thinking) display names

Closes #431

Subject: [PATCH 013/658] fix(backup): create backups only when settings
 content changes

Previously, PUT /api/settings/:profile created a backup on every request
regardless of whether the content actually changed. This led to hundreds
of identical backup files accumulating in ~/.ccs/backups/.

Changes:
- Compare existing content with new content before creating backup
- Reuse computed newContent for atomic write (DRY)
- Make hook injection idempotent by checking content before write

Fixes #433

Subject: [PATCH 015/658] feat(hooks): add image/PDF analysis via CLIProxy
 transformer

Intercept Read tool calls for image/PDF files and route through CLIProxy
with gemini-2.5-flash for vision analysis. Returns text descriptions
instead of blocking, enabling Claude to "see" images via proxy.

Key changes:
- Add image-analyzer-transformer.cjs hook script
- Add ImageAnalysisConfig type and loader
- Add hook installer and profile injector
- Add prompt templates for analysis customization
- Add e2e test suite (excluded from normal CI runs)
- Configure test:e2e script for manual testing

Environment variables:
- CCS_IMAGE_ANALYSIS_ENABLED: Enable/disable (default: 1)
- CCS_IMAGE_ANALYSIS_MODEL: Vision model (default: gemini-2.5-flash)
- CCS_IMAGE_ANALYSIS_TIMEOUT: Timeout in seconds (default: 60)
- CCS_CLIPROXY_API_KEY: API key for CLIProxy auth
- CCS_CLIPROXY_PORT: CLIProxy port (default: 8317)

Closes #426

Subject: [PATCH 019/658] refactor(hooks): use provider_models mapping for
 image analysis
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes ImageAnalysisConfig from providers array to provider_models
mapping for granular vision model control per CLIProxy provider.

Breaking change: config.yaml image_analysis section now uses
provider_models instead of providers/model fields.

Provider-to-model mappings:
- agy → gemini-2.5-flash
- gemini → gemini-2.5-flash
- codex → gpt-5.1-codex-mini
- kiro → kiro-claude-haiku-4-5
- ghcp → claude-haiku-4.5
- claude → claude-haiku-4-5-20251001

Hook checks CCS_CURRENT_PROVIDER against provider_models and skips
if no vision model configured for that provider.

Subject: [PATCH 021/658] fix(update): pre-remove package on Windows bun before
 reinstall

On Windows, bun's global binary symlink may not update properly when
reinstalling the same package. Pre-remove the existing installation
to ensure a clean update, mirroring the dev-install.sh behavior.

Closes #435

Subject: [PATCH 022/658] fix(hooks): add edge case validation in image
 analyzer

- Empty model validation: check `model.trim()` before using
- 10MB boundary: use `>=` instead of `>` for consistent messaging
- Timeout clamping: ensure timeout is between 1-600 seconds
- Response stream error: add error handler for network failures
- Empty response validation: check before JSON.parse to prevent crashes

Subject: [PATCH 024/658] feat(hooks): add UX improvements for image analysis
 hook

Add comprehensive UX enhancements for the image analysis CLIProxy hook:

- Add `ccs config image-analysis` CLI command for managing settings
  - Enable/disable toggle
  - Timeout configuration (10-600s)
  - Per-provider model configuration
  - Status display with provider models

- Add specialized error handlers with actionable messages
  - File too large (with compression hints)
  - CLIProxy unavailable (with start instructions)
  - Auth failure (with re-auth commands)
  - Timeout (with increase timeout hint)
  - Rate limit (with retry guidance)
  - API error (with response body parsing)

- Add comprehensive debug output (CCS_DEBUG=1)
  - Provider name and model
  - File size and media type
  - Timeout and endpoint
  - Skip reasons with context

- Add help text updates
  - `ccs --help` includes Image Analysis section
  - `ccs config --help` lists image-analysis subcommand

- Add doctor integration
  - Validates image_analysis config
  - Checks enabled status, providers, timeout
  - Warns if CLIProxy not running

- Add unit tests for new config command

Subject: [PATCH 025/658] fix(hooks): improve error handling and edge cases for
 image analysis

- Add empty model string validation in config command

- Add --enable/--disable conflict detection

- Truncate long model names in display (>40 chars)

- Add EACCES/EPERM file permission error handler

- Add filesystem error classification (ENOSPC, EROFS)

- Log config upgrade save failures instead of silent catch

Subject: [PATCH 033/658] feat(hooks): inject image analyzer hooks into all
 profile types

Add image analyzer hook injection alongside WebSearch hooks:
- ccs.ts: CLIProxy, Copilot, and API profile flows
- variant-settings.ts: CLIProxy variant settings

Ensures image analyzer hooks are present in profile settings.json files.

Subject: [PATCH 035/658] refactor(hooks): deprecate block-image-read, add
 CLIProxy fallback

- Remove redundant block-image-read.cjs hook (image-analyzer handles all)
- Add fallback blocking when CLIProxy unavailable (prevents context overflow)
- Simplify fallback message to prevent context pollution/hallucination
- Remove image-read-block-hook-env.ts and related exports
- Update comments per PR #442 review suggestions
- Add defensive check for empty models array

Closes #426

-/**
- * CCS Image Read Blocking Hook
- *
- * Blocks Claude's Read tool from reading image files to prevent context overflow.
- * Each image can consume 100K+ tokens, causing immediate context exhaustion.
- *
- * This is a PreToolUse hook that runs BEFORE the tool is executed.
- *
- * Behavior (matches WebSearch pattern):
- * - ENABLED by default for third-party profiles (settings, cliproxy)
- * - DISABLED for native Claude accounts (account, default profiles)
- * - User can override via config: hooks.block_image_read.enabled: false
- *
- * Usage:
- *   Configured in ~/.claude/settings.json:
- *   {
- *     "hooks": {
- *       "PreToolUse": [{
- *         "matcher": "Read",
- *         "hooks": [{
- *           "type": "command",
- *           "command": "node ~/.ccs/hooks/block-image-read.cjs",
- *           "timeout": 5
- *         }]
- *       }]
- *     }
- *   }
- *
- * Environment Variables (set by CCS):
- *   CCS_BLOCK_IMAGE_READ=1    - Enable blocking (default for third-party)
- *   CCS_BLOCK_IMAGE_READ=0    - Disable blocking
- *   CCS_PROFILE_TYPE          - Profile type (account, default, settings, cliproxy)
- *   CCS_DEBUG=1               - Enable debug output
- *
- * Exit codes:
- *   0 - Allow tool (pass-through)
- *   2 - Block tool (deny with message)
- *
- * @module hooks/block-image-read

## [7.35.0](https://github.com/kaitranntt/ccs/compare/v7.34.1...v7.35.0) (2026-02-04)

### ⚠ BREAKING CHANGES

* **hooks:** config.yaml image_analysis section now uses
provider_models instead of providers/model fields.

Provider-to-model mappings:
- agy → gemini-2.5-flash
- gemini → gemini-2.5-flash
- codex → gpt-5.1-codex-mini
- kiro → kiro-claude-haiku-4-5
- ghcp → claude-haiku-4.5
- claude → claude-haiku-4-5-20251001

Hook checks CCS_CURRENT_PROVIDER against provider_models and skips
if no vision model configured for that provider.

### Features

* **hooks:** add ANTHROPIC_MODEL fallback for image analysis ([ae3eb28](https://github.com/kaitranntt/ccs/commit/ae3eb282b4a6a0754f90be27e259af45d0d09d9b))
* **hooks:** add block-image-read hook to prevent context overflow ([38eb740](https://github.com/kaitranntt/ccs/commit/38eb74043c7f9e613e308392b2c159ebfc2a05c1)), closes [#426](https://github.com/kaitranntt/ccs/issues/426)
* **hooks:** add image/PDF analysis via CLIProxy transformer ([d5f2aca](https://github.com/kaitranntt/ccs/commit/d5f2acaa6e9ee5d12a6035c2da1f975551b6a989)), closes [#426](https://github.com/kaitranntt/ccs/issues/426)
* **hooks:** add UX improvements for image analysis hook ([2b0717e](https://github.com/kaitranntt/ccs/commit/2b0717ed53011dcb67cc03ad09a00cfabb682f1e))
* **hooks:** extend image analyzer to all CLIProxy providers ([3252228](https://github.com/kaitranntt/ccs/commit/3252228e5c230d291fc705fb5f1f4b3f58cb2d99))
* **hooks:** inject image analyzer hooks into all profile types ([a8ddf8b](https://github.com/kaitranntt/ccs/commit/a8ddf8bd565ac82131dc4ca02ecadd3b04a61197))
* **hooks:** skip image analyzer for Claude Sub accounts ([26f4021](https://github.com/kaitranntt/ccs/commit/26f40217703800cb412af74195e350090d39e435))
* **ui:** improve settings page UX and responsiveness ([4d87a64](https://github.com/kaitranntt/ccs/commit/4d87a649de3873786926dad0f598d4f481b1b563))

### Bug Fixes

* **backup:** create backups only when settings content changes ([c324e92](https://github.com/kaitranntt/ccs/commit/c324e92eb442669656b53a8f685030f5cb15ce3d)), closes [#433](https://github.com/kaitranntt/ccs/issues/433)
* **checks:** use configurable CLIProxy port in health check ([bfb5350](https://github.com/kaitranntt/ccs/commit/bfb535037ad297b3d838754af74d30b8a88b34f2))
* **cli:** improve network handling and shell escaping ([3c1cf91](https://github.com/kaitranntt/ccs/commit/3c1cf91da4a27e55578a975f02222120a5d3064c))
* **config:** remove unused forceReload parameter in showStatus ([8dfd9e9](https://github.com/kaitranntt/ccs/commit/8dfd9e937599305dcdeab453bb866f16ad582020))
* **delegation:** dynamic model display from settings ([f6b7045](https://github.com/kaitranntt/ccs/commit/f6b7045023e5de52f57fa79445a29de5bfe5a5ff)), closes [#431](https://github.com/kaitranntt/ccs/issues/431)
* **glmt:** gate retry rate limit logs behind verbose flag ([73824bc](https://github.com/kaitranntt/ccs/commit/73824bc99eec2701164837588a231b56b943c536))

+## [7.35.0](https://github.com/kaitranntt/ccs/compare/v7.34.1...v7.35.0) (2026-02-04)
+
+### ⚠ BREAKING CHANGES
+
+* **hooks:** config.yaml image_analysis section now uses
+provider_models instead of providers/model fields.
+
+Provider-to-model mappings:
+- agy → gemini-2.5-flash
+- gemini → gemini-2.5-flash
+- codex → gpt-5.1-codex-mini
+- kiro → kiro-claude-haiku-4-5
+- ghcp → claude-haiku-4.5
+- claude → claude-haiku-4-5-20251001
+
+Hook checks CCS_CURRENT_PROVIDER against provider_models and skips
+if no vision model configured for that provider.
+

Subject: [PATCH 045/658] fix(cliproxy): use os.homedir() for cross-platform
 path expansion

Replace process.env.HOME with os.homedir() when expanding custom
settings paths. On Windows, process.env.HOME is undefined, causing
tilde expansion to produce invalid Unix-style paths like
'/.ccs/variant.settings.json'.

Closes #445

The GLMT retry logic tests use dynamic imports and GlmtProxy
instantiation which are slower on CI runners than locally.
Increase default timeout from 5s to 30s to prevent flaky failures.

Subject: [PATCH 057/658] fix(cliproxy): respect http_proxy env vars for binary
 downloads

CLIProxyAPI installation and updates now respect http_proxy, https_proxy,
and all_proxy environment variables when making network requests.

Uses https-proxy-agent and http-proxy-agent packages to route HTTP/HTTPS
requests through the configured proxy server.

Closes #266

Subject: [PATCH 059/658] test(cliproxy): add comprehensive proxy support unit
 tests

Add 34 unit tests covering:
- getProxyUrl: env var precedence (lowercase > uppercase > all_proxy)
- shouldBypassProxy: wildcard, exact match, suffix patterns, case-insensitivity
- getHostname: URL parsing with error handling
- getProxyAgent: proxy creation, NO_PROXY bypass, error handling

Export internal functions via __testExports for testability.

Subject: [PATCH 064/658] fix(cliproxy): sanitize MCP tool input_schema to
 remove non-standard properties (#459)

Squash merge PR #459: MCP tool input_schema sanitization

Fixes #456 - Gemini/Vertex APIs reject non-standard JSON Schema properties from MCP tools

Changes:
- Add allowlist-based schema sanitizer for JSON Schema Draft-07 keywords
- Recursive sanitization with circular ref protection and depth limit
- Handle all schema containers: properties, items, additionalProperties, additionalItems, oneOf/anyOf/allOf, not, if/then/else, $defs, definitions, patternProperties, contains, propertyNames, dependencies
- 22 unit tests covering edge cases
- Integrates into ToolSanitizationProxy pipeline before tool name sanitization

When in Remote mode, local proxy running status no longer blocks
backend switching. Introduced `isBackendSwitchBlocked` computed

Subject: [PATCH 070/658] fix(doctor): use cmd.exe compatible quoting for
 Windows shell execution

The escapeShellArg function was using PowerShell-style single quotes,
but spawn({ shell: true }) uses cmd.exe by default on Windows.
cmd.exe does not recognize single quotes as string delimiters,
causing 'claude' '--version' to fail.

Changed to use double quotes which work correctly in cmd.exe.

Subject: [PATCH 076/658] refactor(cliproxy): modularize top 4 giant files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split 4 files exceeding 900 lines into focused modules:

- account-manager.ts (961 → 56 lines): 6 modules in accounts/
  - registry, query, bulk-ops, token-file-ops, types, index
- config-generator.ts (981 → 16 lines): 6 modules in config/
  - generator, port-manager, env-builder, thinking-config, path-resolver, index
- cliproxy-executor.ts (1,180 → 21 lines): 5 modules in executor/
  - index, lifecycle-manager, env-resolver, retry-handler, session-bridge
- cliproxy-command.ts (1,297 → 10 lines): 8 modules in commands/cliproxy/
  - index, auth, quota, variant, install, help, proxy-lifecycle subcommands

Total: 4,419 → 103 lines in original files (97.7% reduction)

Backward compatibility maintained via re-export shims.
Edge case fixes: CLI validation, thinking fallback, provider warning.

BREAKING CHANGES: None - all exports preserved via barrel re-exports.

  * CLIProxy Command Handler
  *
- * Manages CLIProxyAPI binary installation and profile variants.
+ * DEPRECATED: This file is a backwards-compatible re-export shim.
+ * The actual implementation has been modularized into src/commands/cliproxy/
  *
- * Binary commands:
- *   ccs cliproxy                  Show current version
- *   ccs cliproxy --install <ver>  Install specific version
- *   ccs cliproxy --latest         Install latest version
- *
- * Profile commands:
- *   ccs cliproxy create <name>    Create CLIProxy variant profile
- *   ccs cliproxy list             List all CLIProxy variant profiles
- *   ccs cliproxy remove <name>    Remove CLIProxy variant profile
- *
- * Supports dual-mode configuration:
- * - Unified YAML format (config.yaml) when CCS_UNIFIED_CONFIG=1 or config.yaml exists
- * - Legacy JSON format (config.json) as fallback
+ * See src/commands/cliproxy/index.ts for the new dispatcher.

Subject: [PATCH 077/658] fix(cliproxy): fix discoverExistingAccounts test
 failures

- Skip saving registry when no new accounts discovered (prevents empty
  accounts.json creation for invalid files)
- Skip merging empty provider sections to prevent empty provider entries
- Update test module cache clearing to include new modular submodules
  (accounts/registry, accounts/index) for proper test isolation

Subject: [PATCH 079/658] fix(ui): display device code for GitHub Copilot OAuth
 in Dashboard

For Device Code OAuth providers (ghcp, qwen), switch from /start-url
to /start endpoint which spawns CLIProxyAPI binary and emits WebSocket
events with userCode. DeviceCodeDialog then displays the code properly.

Subject: [PATCH 080/658] refactor(ui): address PR review feedback for device
 code auth

- Extract INITIAL_STATE constant to reduce code repetition (DRY)
- Remove duplicate success toast for device code flow
  (useDeviceCode already shows toast via deviceCodeCompleted WebSocket event)
- Replace 7 inline state reset objects with INITIAL_STATE reference

Subject: [PATCH 083/658] feat(release): v7.38.0 - Extended Context, Qwen
 Models, Bug Fixes (#480)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(version): show active config path instead of deprecated config.json

The version command was using deprecated getConfigPath() which always
returned config.json path. Now uses getActiveConfigPath() which shows
config.yaml in unified mode or config.json in legacy mode.

* chore(release): 7.37.1-dev.1 [skip ci]

* fix(ui): use native dynamic import to fix Node 24 ESM/CJS interop

TypeScript compiles import() to require() when targeting CommonJS,
which breaks ESM packages like ora on Node 24. Use new Function()
to create native dynamic import at runtime, bypassing TS transform.

Closes #472

* chore(release): 7.37.1-dev.2 [skip ci]

* fix(env): strip ANTHROPIC_* from account/default profiles

Account and default profiles inherit process.env which may contain
stale ANTHROPIC_BASE_URL from prior CLIProxy sessions. This causes
ConnectionRefused errors when Claude tries to hit an unavailable proxy.

Settings-based profiles already handle this by explicitly injecting
their own ANTHROPIC_* values. This fix applies the same protection
to account/default profiles by stripping ANTHROPIC_* before spawn.

Closes #474

* test(env): add unit tests for stripAnthropicEnv

Address code review feedback from PR #475. Tests cover:
- Removing all ANTHROPIC_* keys
- Preserving non-ANTHROPIC keys
- Empty object handling
- Undefined value preservation
- Case sensitivity (only uppercase ANTHROPIC_)
- All ANTHROPIC_ prefixed variants stripped

* chore(release): 7.37.1-dev.3 [skip ci]

* feat(cliproxy): add extended context support for 1M token window

Add --1m and --no-1m flags to enable/disable 1M token context window.
Uses Claude Code's [1m] suffix mechanism.

Behavior:
- Gemini models: auto-enabled by default
- Claude models: opt-in with --1m flag
- New extendedContext field in model catalog

Also adds Claude Opus 4.6 to model catalog with extended context support.

Closes #103

* feat(ui): add extended context toggle in dashboard model config

- Add ExtendedContextToggle component for 1M token context window
- Add Claude Opus 4.6 (claude-opus-4-6-20260203) to model catalogs
- Mark Gemini and Claude models with extendedContext: true
- Toggle only appears when selected model supports extended context
- Auto-enabled info for native Gemini, opt-in info for Claude

Part of extended context feature implementation for issue #103.

* fix: address code review findings and CI failure

- Fix CI error: add missing 'provider' prop to ModelConfigSection
- Fix case sensitivity in applyExtendedContextSuffix
- Fix whitespace handling in stripModelSuffixes
- Handle --1m=value and --no-1m=value CLI patterns
- Add warning when --1m used on unsupported model
- Sync agy catalog: add extendedContext to gemini-3-pro-preview
- Extract isNativeGeminiModel to shared utility (DRY)
- Add 21 unit tests for extended-context-config

* fix(catalog): rename claude-opus-4-6-20260203 to claude-opus-4-6

* fix(ui): wire extended context toggle through component tree

- Add extendedContextEnabled and toggleExtendedContext to useProviderEditor hook
- Store setting as CCS_EXTENDED_CONTEXT env var in provider settings
- Pass props through provider-editor → model-config-tab → model-config-section
- Update UseProviderEditorReturn type with new properties

* fix(ui): apply [1m] suffix directly to model strings in settings

- Toggle now applies/strips [1m] suffix to all ANTHROPIC_*MODEL env vars
- Extended context detected by checking if any model has [1m] suffix
- Remove legacy CCS_EXTENDED_CONTEXT flag approach
- Add suffix utilities: applyExtendedContextSuffix, stripExtendedContextSuffix
- Raw Configuration now shows actual model values with [1m] suffix

* fix(qwen): update model catalog with correct context windows and tier mappings

- Update context window specs from official Alibaba docs:
  - Qwen3 Coder Plus: 1M context (was 32K)
  - Qwen3 Max: 256K context (flagship)
  - Qwen3 Coder Flash: fast code generation
- Fix preset mappings for Claude tier equivalence:
  - Opus → qwen3-max (flagship 256K)
  - Sonnet → qwen3-coder-plus (balanced 1M)
  - Haiku → qwen3-coder-flash (fast)
- Update provider descriptions to reflect 256K-1M context range
- Add all 7 Qwen models from CLIProxyAPI: qwen3-coder-plus, qwen3-max,
  qwen3-max-preview, qwen3-235b, qwen3-vl-plus, qwen3-coder-flash, qwen3-32b

Closes #478

* fix(ui): only apply [1m] suffix to ANTHROPIC_MODEL, fix toggle refresh

- Only ANTHROPIC_MODEL gets [1m] suffix, not tier mappings
- Strip [1m] when looking up model in catalog to prevent toggle disappearing
- Fix odd page refresh when toggling extended context

* chore(release): 7.37.1-dev.4 [skip ci]

* fix(ui): remove duplicate import in use-provider-editor

* chore: address PR review feedback - sync comment and unused import

* chore(release): 7.37.1-dev.5 [skip ci]

* feat(cliproxy): add Opus 4.6 to Antigravity model catalog (#482)

* feat(cliproxy): add Opus 4.6 to Antigravity model catalog

- Add gemini-claude-opus-4-6-thinking as new default agy model
- Update preset mappings to route opus tier to Opus 4.6
- Bump CLIProxy fallback versions to v6.8.2
- Keep Opus 4.5 as previous flagship option

* fix(cliproxy): include oauth-model-alias in config generation

Root cause: CLIProxy config.yaml was missing Opus 4.6 alias because:
1. CLIProxyPlus startup migration is disabled (intentional)
2. CCS config generator never wrote oauth-model-alias section
3. Existing users with outdated aliases got 502 on Opus 4.6

Fix:
- Add DEFAULT_ANTIGRAVITY_ALIASES to config generator
- Generate oauth-model-alias section in config.yaml template
- Preserve claude-api-key and custom aliases during regeneration
- Bump config version to v6 to trigger auto-regeneration
- Update model catalog tests for new model count

* fix(cliproxy): preserve YAML indentation in extractYamlSection

- Replace .trim() with regex to strip only leading/trailing newlines,
  preserving 2-space indent on claude-api-key children
- Skip standalone comments at col 0 in section boundary detection
- Update stale test description (4 → 5 models)

* chore(release): 7.37.1-dev.6 [skip ci]

Subject: [PATCH 085/658] fix(teams): propagate CLAUDE_CONFIG_DIR to tmux
 session for agent teammates

When CCS launches Claude with CLAUDE_CONFIG_DIR pointing to the isolated
instance path, agent team teammates spawned via tmux split-window don't
inherit it because tmux creates new panes from its own session environment.
This causes teammates to use ~/.claude/ instead of ~/.ccs/instances/{profile}/,
creating a split-brain in shared state (tasks, teams, mailbox).

Sets key CCS env vars in the tmux session environment via `tmux setenv` so
all new panes inherit the correct config directory.

Subject: [PATCH 088/658] feat(cliproxy): add hybrid catalog sync with
 CLIProxyAPI (#485)

* chore(release): 7.38.0 [skip ci]

## [7.38.0](https://github.com/kaitranntt/ccs/compare/v7.37.1...v7.38.0) (2026-02-07)

### Features

* **release:** v7.38.0 - Extended Context, Qwen Models, Bug Fixes ([#480](https://github.com/kaitranntt/ccs/issues/480)) ([b454834](https://github.com/kaitranntt/ccs/commit/b4548341750804339c87c48259dd8741425d2acf)), closes [#472](https://github.com/kaitranntt/ccs/issues/472) [#474](https://github.com/kaitranntt/ccs/issues/474) [#103](https://github.com/kaitranntt/ccs/issues/103) [#478](https://github.com/kaitranntt/ccs/issues/478) [#482](https://github.com/kaitranntt/ccs/issues/482)

* feat(cliproxy): add hybrid catalog sync with CLIProxyAPI

Add `ccs cliproxy catalog` command family for syncing model catalogs
from CLIProxyAPI's model-definitions endpoint. Cached locally with
24h TTL, merges remote models with static catalog preserving
broken/deprecated flags. Dashboard API endpoint at /api/cliproxy/catalog.

Closes #477

Subject: [PATCH 091/658] fix(hooks): add image analysis env vars for

## [7.38.0](https://github.com/kaitranntt/ccs/compare/v7.37.1...v7.38.0) (2026-02-07)

### Features

* **release:** v7.38.0 - Extended Context, Qwen Models, Bug Fixes ([#480](https://github.com/kaitranntt/ccs/issues/480)) ([b454834](https://github.com/kaitranntt/ccs/commit/b4548341750804339c87c48259dd8741425d2acf)), closes [#472](https://github.com/kaitranntt/ccs/issues/472) [#474](https://github.com/kaitranntt/ccs/issues/474) [#103](https://github.com/kaitranntt/ccs/issues/103) [#478](https://github.com/kaitranntt/ccs/issues/478) [#482](https://github.com/kaitranntt/ccs/issues/482)

* fix(hooks): add image analysis env vars for settings-based profiles

Image analysis hook was injected into settings files for API profiles
but the CCS_IMAGE_ANALYSIS_* env vars were never set, causing the hook
to skip. Add getImageAnalysisHookEnv() call to both settings-based and
GLMT proxy execution paths, matching CLIProxy profile behavior.

Closes #440

* fix(hooks): add hook env vars to copilot executor

Copilot profile had same gap as settings-based profiles: hooks installed
but webSearch/imageAnalysis env vars and CCS_PROFILE_TYPE never set.
Add missing env var injection matching other profile flows.

Subject: [PATCH 093/658] feat: hybrid CLIProxy catalog sync + agent teams env
 fix (#486)

* fix(teams): propagate CLAUDE_CONFIG_DIR to tmux session for agent teammates

When CCS launches Claude with CLAUDE_CONFIG_DIR pointing to the isolated
instance path, agent team teammates spawned via tmux split-window don't
inherit it because tmux creates new panes from its own session environment.
This causes teammates to use ~/.claude/ instead of ~/.ccs/instances/{profile}/,
creating a split-brain in shared state (tasks, teams, mailbox).

Sets key CCS env vars in the tmux session environment via `tmux setenv` so
all new panes inherit the correct config directory.

* refactor(teams): use spawnSync array args instead of execSync string

Avoids shell interpretation of env values by passing args as array
to spawnSync instead of interpolating into a shell command string.

* chore(release): 7.38.0-dev.1 [skip ci]

* feat(cliproxy): add hybrid catalog sync with CLIProxyAPI (#485)

* chore(release): 7.38.0 [skip ci]

## [7.38.0](https://github.com/kaitranntt/ccs/compare/v7.37.1...v7.38.0) (2026-02-07)

* feat(cliproxy): add hybrid catalog sync with CLIProxyAPI

Add `ccs cliproxy catalog` command family for syncing model catalogs
from CLIProxyAPI's model-definitions endpoint. Cached locally with
24h TTL, merges remote models with static catalog preserving
broken/deprecated flags. Dashboard API endpoint at /api/cliproxy/catalog.

Subject: [PATCH 096/658] feat(cliproxy): delegate kiro/ghcp token refresh to
 CLIProxyAPIPlus (#488)

CLIProxyAPIPlus already handles background token refresh for kiro (every
1 min via background_refresh.go) and other providers. CCS was incorrectly
returning "not implemented" errors for these providers, causing noisy
worker logs and preventing proper token expiry tracking.

Changes:
- Classify providers into CCS-managed (gemini), CLIProxy-delegated
  (codex, agy, kiro, ghcp, qwen, iflow), and not-implemented (claude)
- Delegated providers return success with delegated flag instead of error
- Skip refresh_token requirement for delegated providers in expiry checker
- Filter delegated providers from background worker refresh loop

Closes #487

Subject: [PATCH 098/658] fix(cliproxy): guard against empty upstream SSE
 responses in agy profile (#489)

* fix(cliproxy): guard against empty upstream SSE responses in agy profile

When CLIProxyAPIPlus drops unsigned thinking blocks during sub-agent
execution, the response stream can contain no content_block_start or
message_delta events. This causes Claude Code CLI to crash with
"No assistant message found".

Add empty response detection in the tool sanitization proxy's streaming
handler. Both the pipe-through and SSE-processing paths now track
whether meaningful content was received. If upstream sent data but no
content blocks on a 200 OK, a synthetic minimal valid SSE response is
injected to prevent the client crash and surface a clear error message.

Closes #350

* fix(cliproxy): improve empty response detection and add tests

Address code review findings:
- Remove message_delta from content detection (lifecycle event, not
  content); only content_block_start indicates actual content
- Add try-catch in end handlers to handle client disconnects gracefully
- Add 3 integration tests: empty stream injection, normal stream
  passthrough, 4xx/5xx non-injection

* fix(cliproxy): avoid duplicate message_start in synthetic response

Track whether upstream already sent a message_start event. When
injecting the synthetic error response, omit message_start if upstream
already sent one, preventing duplicate events in the SSE stream.

Addresses PR review feedback from ccs-reviewer[bot].

* test(cliproxy): add SSE processing path and real failure mode tests

Address code review observations:
- Add test exercising SSE processing path (sanitized tool names) for
  empty response detection, ensuring both code paths are covered
- Add test mirroring real failure mode where upstream sends only
  message_start then ends abruptly (no message_delta/message_stop)
- Document duplicate message_start assumption with inline comment

Subject: [PATCH 100/658] fix(cliproxy): disable 1M extended context for opus
 4.6 (256k limit) (#492)

* fix(cliproxy): disable 1M extended context for gemini-claude-opus-4-6-thinking

Antigravity backend only supports 256k context window for this model,
not 1M as previously declared. Set extendedContext: false with TODO
comment for easy re-enable when backend adds support.

Closes #490

* fix(cliproxy): strip [1m] suffix at runtime for models without extended context

Users with existing [1m] in saved agy.settings.json will now have it
automatically stripped at runtime when the model no longer supports
extended context. Prevents misleading context window claims.

Subject: [PATCH 102/658] refactor(cliproxy): deduplicate
 message_delta/message_stop in synthetic SSE response

Track hasReceivedMessageDelta and hasReceivedMessageStop in both
streaming paths (pipe-through and SSE-processing). Conditionally
omit these events from buildSyntheticErrorResponse() when upstream
already sent them, preventing protocol violations.

Subject: [PATCH 103/658] refactor(cliproxy): check lifecycle events in
 remaining SSE buffer

Add message_start/message_delta/message_stop detection to the
remaining-buffer block in the SSE processing path for defensive
completeness. Addresses code review feedback on PR #493.

Subject: [PATCH 105/658] refactor(cliproxy): extract SSE lifecycle tracker and
 add backpressure handling

Consolidate 5 duplicate boolean tracking variables into a lifecycle
object with an update() method, reducing event detection from 4
locations to centralized calls. Add pause/drain/resume backpressure
to the passthrough path to prevent unbounded memory buffering with
slow clients.

Subject: [PATCH 108/658] fix(cliproxy): strip Gemini-unsupported schema fields
 including "examples"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace permissive JSON Schema Draft-07 whitelist with strict
Gemini-compatible field set (22 fields). The "examples" field
in Claude Code tool schemas caused 400 errors from Gemini API.

Also strips other unsupported fields: $ref, $defs, oneOf, allOf,
additionalProperties, const, if/then/else, etc.

Safe change — sanitizer only runs for CLIProxy profiles (Gemini,
Codex, Antigravity), never for direct Anthropic API requests.

Closes #155

Subject: [PATCH 109/658] test(cliproxy): add edge case coverage for Gemini
 schema sanitizer

Add tests for: exclusiveMinimum/exclusiveMaximum/multipleOf stripping,
uniqueItems/contains/additionalItems stripping, writeOnly/definitions
stripping, example with array values, default with complex nested
objects, empty properties/anyOf edge cases.

Fix proxy log message to say "Gemini-unsupported" instead of
"non-standard".

 device code flow

- Escalate SIGTERM to SIGKILL after 3s if Go binary is stuck in blocking HTTP call
- Extend timeout to 300s for device code flows matching CLIProxy binary polling window
- Apply SIGKILL escalation to both SIGINT cleanup and timeout handlers

Closes #314

Subject: [PATCH 118/658] feat(env): add ccs env command for third-party tool
 integration

New `ccs env <profile>` command exports shell-evaluable environment
variables for OpenCode, Cursor, Continue, and other third-party tools.

Supports --format (openai|anthropic|raw) and --shell (auto|bash|fish|
powershell) flags. Auto-detects shell from $SHELL env var.

Closes #503

consumed via eval. Also fix parseFlag to handle values containing =,
remove unused test imports, and add empty-output guard after format
transformation.

Subject: [PATCH 120/658] fix(env): add key sanitization and shell completions

- Validate env var keys match ^[A-Za-z_][A-Za-z0-9_]*$ before output
  to prevent injection via crafted config files
- Add env command to all 4 shell completion scripts (bash, zsh, fish,
  PowerShell) with sub-completions for --format and --shell flags

Subject: [PATCH 123/658] fix(env): fix fish escaping, profile parsing, and add
 OPENAI_MODEL mapping

- Fix P0: fish single-quote escaping uses '\'' (end-quote, literal, reopen)
  instead of \' which fish doesn't support inside single-quoted strings
- Fix P0: profile arg parsing now skips flag values via findProfile() so
  `ccs env --format openai gemini` correctly resolves to 'gemini'
- Add OPENAI_MODEL mapping from ANTHROPIC_MODEL in transformToOpenAI
- Add stderr warning when invalid env var keys are silently dropped
- Update --shell help text to mention zsh compatibility
- Add findProfile tests (6) and OPENAI_MODEL omission test

Subject: [PATCH 124/658] fix(env): address P1-P3 review items from code review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- P1: Fix bash completion $cliproxy_profiles scoping — inline profiles
  in env block since variable is only defined at COMP_CWORD=1 scope
- P2: Detect account-based profiles and show specific error message
  instead of generic "not found"
- P2: Show `ccs migrate` hint when unified mode is disabled and settings
  profile resolution fails
- P2: transformToOpenAI omits empty entries at transform time instead of
  relying on output filter (removes fragile coupling)
- P3: Add zsh and auto to --shell completions across all 4 shells; map
  --shell zsh to bash in command handler since syntax is identical
- P3: Auto-detect PowerShell from SHELL containing pwsh on non-Windows
- Tests: 33 pass (+1 pwsh detection test, updated transform assertions)

Subject: [PATCH 127/658] feat(config): add CCS_DIR env var and --config-dir
 flag for config directory override

Allow users to relocate the entire ~/.ccs/ directory via CCS_DIR env var
or --config-dir CLI flag. Precedence: --config-dir > CCS_DIR > CCS_HOME > default.
Includes cloud sync path detection warning and doctor diagnostics.

Closes #507

 completions and improve error messages

- Add profile name completions to fish env subcommand
- Add iflow, kiro, ghcp, claude to zsh proxy_profiles and PS1 cliproxyProfiles
- Distinguish non-API profile type error from "profile not found"

Subject: [PATCH 129/658] fix(config): migrate all hardcoded paths to
 getCcsDir() and improve validation

- Replace os.homedir() + '.ccs' with getCcsDir() across 14 instances in 13 files:
  version-command, model-config, openrouter-catalog, config-checks, disk-cache,
  aggregator, auth-middleware, shell-completion, shared-manager, recovery-manager,
  auto-repair, delegation-validator, claude-dir-installer, cliproxy executor
- Add isDirectory() validation for --config-dir argument in ccs.ts
- Make detectCloudSyncPath() case-insensitive for cloud provider matching
- Fix help-command.ts to use dynamic dirDisplay for all path references
- Add 5 new tests: setGlobalConfigDir precedence, relative path resolution,
  reset behavior, getCcsDirSource with --config-dir, case-insensitive detection
- Clean up unused os imports after migration

Subject: [PATCH 131/658] fix(config): lazy-evaluate paths, fix TOCTOU,
 segment-boundary cloud detection

- Convert 4 module-level constants to lazy-evaluated functions to avoid
  import-time caching: openrouter-catalog, aggregator, disk-cache, auth-middleware
- Fix symlink-checks.ts to use ccsDir parameter instead of homedir/.ccs,
  remove unused homedir parameter from checkSettingsSymlinks()
- Replace TOCTOU existsSync+statSync with single statSync in try/catch
  for --config-dir validation in ccs.ts
- Switch detectCloudSyncPath from substring to path-segment-boundary matching
  to prevent false positives (e.g., megauser != MEGA, Dropbox-api != Dropbox)
- Add test for false-positive protection

Subject: [PATCH 133/658] fix(config): resolve remaining hardcoded paths and
 improve readability

- Replace hardcoded ~/.ccs in error messages: ccs.ts (lines 83, 151)
  and delegation-handler.ts (line 333) now use getCcsDir()
- Cache repeated getter calls in local vars for readability:
  openrouter-catalog.ts getCachedModels/setCachedModels,
  aggregator.ts getInstancePaths
- Add path.resolve() for CCS_HOME env var consistency with CCS_DIR

Subject: [PATCH 134/658] refactor(config): DRY precedence logic, dynamic
 recovery messages, CCS_HOME cloud warning

- Extract shared _resolveCcsDir() to prevent getCcsDir/getCcsDirSource divergence
- Replace all hardcoded ~/.ccs/ and ~/.claude/ in recovery-manager.ts with
  dynamic paths from instance properties (ccsDir, claudeDir, sharedDir, etc.)
- Add cloud sync detection for CCS_HOME env var (parity with CCS_DIR/--config-dir)
- Cache getSessionSecretPath() in local var in auth-middleware.ts
- Cache getCacheDir() in local var in disk-cache.ts ensureCacheDir()

Subject: [PATCH 135/658] fix(config): dynamic health message, cache getters,
 static imports, cloud hint

- Fix hardcoded 'Created ~/.ccs directory' in health-service.ts fixHealthIssue()
- Cache getCacheFile() in local vars: readDiskCache, writeDiskCache, clearDiskCache
- Convert dynamic imports of setGlobalConfigDir/detectCloudSyncPath to static
- Add remediation hint to cloud sync warning: 'Consider: CCS_DIR=/path/outside/cloud'

## [7.41.0](https://github.com/kaitranntt/ccs/compare/v7.40.0...v7.41.0) (2026-02-11)

### Features

* **config:** add CCS_DIR env var and --config-dir flag for config directory override ([7a0e6a4](https://github.com/kaitranntt/ccs/commit/7a0e6a4112b50dad14bf48004b07a77d1a5fd4d8)), closes [#507](https://github.com/kaitranntt/ccs/issues/507)
* **env:** add ccs env command for third-party tool integration ([2e85064](https://github.com/kaitranntt/ccs/commit/2e85064b8a6a3eed694abb56bef70bf889f648d3)), closes [#503](https://github.com/kaitranntt/ccs/issues/503)
* update cliproxy, config loader, glmt transformer, and provider routes ([8c6afe2](https://github.com/kaitranntt/ccs/commit/8c6afe2e73049ecfbb12cb29a894e83eb2576354))

### Bug Fixes

* **cliproxy:** prevent OAuth process hang on Qwen device code flow ([086bf95](https://github.com/kaitranntt/ccs/commit/086bf958e9c6c9d6d745e78a29a95a9a58490bf1)), closes [#314](https://github.com/kaitranntt/ccs/issues/314)
* **cliproxy:** strip Gemini-unsupported schema fields including "examples" ([505d6d0](https://github.com/kaitranntt/ccs/commit/505d6d0f111b11e4e231742d65d2a3bbfb73864a)), closes [#155](https://github.com/kaitranntt/ccs/issues/155)
* **config:** dynamic health message, cache getters, static imports, cloud hint ([706cca8](https://github.com/kaitranntt/ccs/commit/706cca8b3e57c1f9e6c559dc4c1a18ed6854a96d))
* **config:** lazy-evaluate paths, fix TOCTOU, segment-boundary cloud detection ([d5abc7d](https://github.com/kaitranntt/ccs/commit/d5abc7d69170132cc5c604c453e45f54fa2973b6))
* **config:** migrate all hardcoded paths to getCcsDir() and improve validation ([60d6bbd](https://github.com/kaitranntt/ccs/commit/60d6bbd0271a4bad4df1eaa705c11d34f7abd464))
* **config:** resolve remaining hardcoded paths and improve readability ([c8800b4](https://github.com/kaitranntt/ccs/commit/c8800b418a8ee2143366a2e199c42384ff5693f4))
* **delegation:** use exitCode instead of killed for process termination checks ([4b1fcac](https://github.com/kaitranntt/ccs/commit/4b1fcacf307e0bb8935495202f0322210eb395ea))
* **env:** add key sanitization and shell completions ([76457a5](https://github.com/kaitranntt/ccs/commit/76457a567d7d1fe52a983a3c6e37b49d503071c9))
* **env:** add missing CLIProxy profiles to bash completion and shell validation ([6d9351d](https://github.com/kaitranntt/ccs/commit/6d9351dcbc1baa4135d75361301e36cafc3556a3))
* **env:** address all PR review feedback ([44b3152](https://github.com/kaitranntt/ccs/commit/44b3152d347a7f0c96af4e2e4cd8027ea30634fc))

Subject: [PATCH 140/658] fix(cliproxy): migrate deprecated gemini-claude-*
 model names to upstream claude-* names (#515)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cliproxy): migrate deprecated gemini-claude-* model names to upstream claude-* names

CLIProxyAPI registry no longer recognizes the gemini-claude-* prefix convention.
Model names in catalog, base config, and user settings are migrated to upstream
claude-* names. Auto-migration in env-builder rewrites existing user settings on
load and persists the change.

Closes #513

* fix: address code review feedback — sync UI layer and add migration tests

- Sync UI isNativeGeminiModel() with backend (remove gemini-claude- exclusion)
- Update UI model catalog agy entries from gemini-claude-* to claude-*
- Update CI/CD workflow and code-reviewer default model names
- Add unit tests for migrateDeprecatedModelNames() logic

Subject: [PATCH 141/658] fix(hooks): isolate image type check before
 error-prone processing (#514)

* fix(hooks): isolate image type check before error-prone processing

Restructure processHook() into two phases so non-image Read calls
never see hook error messages. Phase 1 defensively checks tool name
and file extension, exiting 0 silently on any failure. Phase 2 only
runs for confirmed image/PDF files where errors are relevant.

Closes #511

* fix(hooks): sync image analyzer hook file on every profile launch

Add installImageAnalyzerHook() call to cliproxy executor, matching
the existing installWebSearchHook() pattern. This ensures the .cjs
file in ~/.ccs/hooks/ gets refreshed from the npm package on every
launch, so users receive hook updates after npm update.

Subject: [PATCH 143/658] feat(cursor): add auth module with SQLite auto-detect
 and types

- Add CursorCredentials, CursorAuthStatus, and related types
- Implement autoDetectTokens() using sqlite3 CLI (no native deps)
- Add validateToken() for token format validation
- Add extractUserInfo() for JWT decoding
- Add saveCredentials/loadCredentials using getCcsDir()
- Add checkAuthStatus() for auth verification
- Platform-specific state.vscdb paths (Linux/macOS/Windows)
- Graceful error handling for missing database/tokens

Subject: [PATCH 144/658] feat(cursor): add core protobuf encoder/decoder and
 executor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Split protobuf into 3 files: schema, encoder, decoder for <200 LOC constraint
- Implement ConnectRPC wire format encoding (varint, fields, messages, frames)
- Implement protobuf decoder with gzip decompression support
- Port Cursor executor with HTTP/2 support and checksum generation (Jyh cipher)
- Add OpenAI to Cursor message translator (system→user, tool results handling)
- Transform protobuf responses to both SSE and JSON formats
- Use Node.js built-in crypto/zlib (no uuid dependency)
- All files TypeScript strict mode compliant

Subject: [PATCH 147/658] feat(cursor): add daemon lifecycle, models catalog,
 and CLI commands

Implements #520 - Cursor IDE daemon, models catalog, module index, and CLI.

Files created:
- src/cursor/cursor-daemon.ts (~230 LOC) - Lifecycle management (start/stop/status)
- src/cursor/cursor-models.ts (~145 LOC) - Model catalog with Anthropic/OpenAI/Google/Cursor models
- src/cursor/index.ts (~30 LOC) - Module barrel exports
- src/commands/cursor-command.ts (~230 LOC) - CLI commands (auth/status/models/start/stop)

Key features:
- Daemon health checks via HTTP /health endpoint
- PID file management in ~/.ccs/cursor/daemon.pid
- Model catalog with fetchModelsFromDaemon() and fallback defaults
- CLI subcommand routing following copilot-command.ts pattern
- ASCII-only output ([OK], [X], [i] markers)

Temporary defaults for config (port: 4242, model: gpt-4.1) until #521 adds
cursor to unified config schema.

Note: Actual daemon server implementation (CursorExecutor integration) deferred
to #522 - this creates the lifecycle structure only.

Subject: [PATCH 149/658] fix(cliproxy): add fork:true for Claude model aliases
 in config generator (#523)

Config generator now outputs fork:true for Claude model alias entries,
ensuring both upstream (claude-*) and aliased (gemini-claude-*) model
names appear in /v1/models listings. Also preserves fork flag when
parsing user-added aliases during config regeneration.

Bumps config version to v7 to trigger regeneration on next ccs doctor.

Closes #522

Subject: [PATCH 153/658] fix(cursor): fix test isolation and daemon exit
 handling

- Convert PID_FILE constant to getPidFilePath() function to respect CCS_HOME changes at runtime
- Add proc.on('exit') handler to clear interval on silent process crashes
- Ensures test isolation by computing paths dynamically

Subject: [PATCH 154/658] fix(cursor): address code review edge cases in
 protobuf and executor

CRITICAL FIX:
- CursorCredentials interface now matches types.ts (machineId, ghostMode as top-level)
- Fixes runtime error when cursor-auth saves credentials and cursor-executor reads them

HIGH:
- Replace 18+ non-null assertions with guard clauses across executor and decoder
- Prefix unused params in translator (_model, _stream, _credentials)
- HTTP/2 client closes on connection error to prevent leak
- AbortSignal listener leak documented with TODO (inline arrow prevents cleanup)

MEDIUM:
- Export concatArrays from encoder, remove duplicate from protobuf.ts
- Varint decoder now enforces 5-byte max to prevent overflow
- Buffer slice bounds check prevents out-of-range read
- Empty messages array validation with explicit error
- Buffered streaming limitation documented with TODO comment

All edge cases from code review now addressed.

Subject: [PATCH 155/658] feat(cliproxy): add account safety guards to prevent
 Google account bans (#516)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(cliproxy): add account safety guards to prevent Google account bans

Implements cross-provider isolation to prevent Google from flagging
concurrent OAuth usage across different client IDs (ref: #509, #512).

Three pillars:
1. Auto-pause enforcement at session launch — conflicting accounts in
   other Google OAuth providers are paused so CLIProxyAPI can't use them,
   restored on session exit with crash recovery via auto-paused.json
2. Ban/disable detection — error responses matching Google ban patterns
   auto-pause the affected account to prevent further damage
3. Cross-provider conflict warnings during OAuth registration

Key design decisions:
- PID-based session tracking for crash recovery (dead PID = restore)
- Timestamp comparison prevents restoring ban-paused accounts on exit
- Schema validation on auto-paused.json prevents corrupted state
- Falls back to warn-only when another session is managing isolation

* fix(cliproxy): address code review feedback (attempt 1/5)

- Re-read auto-paused.json before write in enforceProviderIsolation to
  reduce concurrent write race window
- Use actual email from registry for display instead of raw accountId
- Export maskEmail for testability
- Add 27 unit tests covering ban detection, email masking,
  cross-provider duplicate detection, enforcement lifecycle,
  crash recovery, and timestamp-guarded restore

* fix(cliproxy): address remaining review feedback (attempt 2/5)

- Add handleBanDetection test verifying account pause on ban error
- Add warnCrossProviderDuplicates tests (true/false/non-Google)
- Document PID reuse limitation in isPidAlive JSDoc comment

Subject: [PATCH 157/658] fix(cursor): address code review feedback (attempt
 1/5)

- Fix bitwise shift overflow in generateChecksum: use Math.trunc
  division for >>40/>>32 which wrap modulo 32 in JS
- Add FIXED64/FIXED32 bounds checks in protobuf decoder to prevent
  out-of-bounds slice on truncated buffers
- Consolidate COMPRESS_FLAG to single definition in schema (DRY):
  executor now imports from schema, added GZIP_ALT/GZIP_BOTH values
- Fix token split edge case: use indexOf+slice instead of split('::')[1]
  to handle tokens containing multiple :: delimiters
- Fix AbortSignal listener leak: store handler ref, use once:true,
  remove listener on request end/error

Subject: [PATCH 159/658] feat(cliproxy): runtime quota monitoring during
 active sessions (#529)

* feat(cliproxy): add runtime quota monitoring during active sessions

Adds adaptive background quota polling to detect and respond to quota
exhaustion during active CLIProxy sessions. Prevents rate-limit-driven
account bans by auto-cooling exhausted accounts and switching defaults.

- Adaptive polling: 300s normal, 60s at 20% threshold, stops at 0%
- Stderr warnings at 20%, boxed exhaustion alerts at 0%
- Cooldown + default switch on exhaustion (existing patterns)
- Configurable via quota_management.runtime_monitor in config.yaml
- Timer.unref() prevents blocking process exit
- monitorStopped guard for in-flight poll safety

Closes #524

* fix: address code review feedback (attempt 1/5)

- M1: Round quotaPercent display with Math.round() to avoid ugly floats
- M2: Rename exhaust_threshold -> exhaustion_threshold for consistency
  with existing auto.exhaustion_threshold config field
- M3: Replace async not.toThrow() with direct await assertion pattern

* fix: address code review feedback (attempt 2/5)

- Remove .claude/agent-memory/ from tracking and add to .gitignore
- Unify cooldown_minutes default to 5 (was 10 in runtime_monitor, 5 in auto)
- Add threshold validation in startQuotaMonitor (warn > exhaustion)
- Document intentional post-switch monitoring gap in code comment

Subject: [PATCH 165/658] feat: account safety, quota monitoring, and stability
 fixes (#530)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cliproxy): migrate deprecated gemini-claude-* model names to upstream claude-* names (#515)

* fix(cliproxy): migrate deprecated gemini-claude-* model names to upstream claude-* names

CLIProxyAPI registry no longer recognizes the gemini-claude-* prefix convention.
Model names in catalog, base config, and user settings are migrated to upstream
claude-* names. Auto-migration in env-builder rewrites existing user settings on
load and persists the change.

Closes #513

* fix: address code review feedback — sync UI layer and add migration tests

- Sync UI isNativeGeminiModel() with backend (remove gemini-claude- exclusion)
- Update UI model catalog agy entries from gemini-claude-* to claude-*
- Update CI/CD workflow and code-reviewer default model names
- Add unit tests for migrateDeprecatedModelNames() logic

* fix(hooks): isolate image type check before error-prone processing (#514)

* fix(hooks): isolate image type check before error-prone processing

Restructure processHook() into two phases so non-image Read calls
never see hook error messages. Phase 1 defensively checks tool name
and file extension, exiting 0 silently on any failure. Phase 2 only
runs for confirmed image/PDF files where errors are relevant.

Closes #511

* fix(hooks): sync image analyzer hook file on every profile launch

Add installImageAnalyzerHook() call to cliproxy executor, matching
the existing installWebSearchHook() pattern. This ensures the .cjs
file in ~/.ccs/hooks/ gets refreshed from the npm package on every
launch, so users receive hook updates after npm update.

* chore(release): 7.41.0-dev.1 [skip ci]

* fix(cliproxy): add fork:true for Claude model aliases in config generator (#523)

Config generator now outputs fork:true for Claude model alias entries,
ensuring both upstream (claude-*) and aliased (gemini-claude-*) model
names appear in /v1/models listings. Also preserves fork flag when
parsing user-added aliases during config regeneration.

Bumps config version to v7 to trigger regeneration on next ccs doctor.

Closes #522

* chore(release): 7.41.0-dev.2 [skip ci]

* feat(cliproxy): add account safety guards to prevent Google account bans (#516)

* feat(cliproxy): add account safety guards to prevent Google account bans

Implements cross-provider isolation to prevent Google from flagging
concurrent OAuth usage across different client IDs (ref: #509, #512).

Three pillars:
1. Auto-pause enforcement at session launch — conflicting accounts in
   other Google OAuth providers are paused so CLIProxyAPI can't use them,
   restored on session exit with crash recovery via auto-paused.json
2. Ban/disable detection — error responses matching Google ban patterns
   auto-pause the affected account to prevent further damage
3. Cross-provider conflict warnings during OAuth registration

Key design decisions:
- PID-based session tracking for crash recovery (dead PID = restore)
- Timestamp comparison prevents restoring ban-paused accounts on exit
- Schema validation on auto-paused.json prevents corrupted state
- Falls back to warn-only when another session is managing isolation

* fix(cliproxy): address code review feedback (attempt 1/5)

- Re-read auto-paused.json before write in enforceProviderIsolation to
  reduce concurrent write race window
- Use actual email from registry for display instead of raw accountId
- Export maskEmail for testability
- Add 27 unit tests covering ban detection, email masking,
  cross-provider duplicate detection, enforcement lifecycle,
  crash recovery, and timestamp-guarded restore

* fix(cliproxy): address remaining review feedback (attempt 2/5)

- Add handleBanDetection test verifying account pause on ban error
- Add warnCrossProviderDuplicates tests (true/false/non-Google)
- Document PID reuse limitation in isPidAlive JSDoc comment

* chore(release): 7.41.0-dev.3 [skip ci]

* feat(cliproxy): runtime quota monitoring during active sessions (#529)

* feat(cliproxy): add runtime quota monitoring during active sessions

Adds adaptive background quota polling to detect and respond to quota
exhaustion during active CLIProxy sessions. Prevents rate-limit-driven
account bans by auto-cooling exhausted accounts and switching defaults.

- Adaptive polling: 300s normal, 60s at 20% threshold, stops at 0%
- Stderr warnings at 20%, boxed exhaustion alerts at 0%
- Cooldown + default switch on exhaustion (existing patterns)
- Configurable via quota_management.runtime_monitor in config.yaml
- Timer.unref() prevents blocking process exit
- monitorStopped guard for in-flight poll safety

Closes #524

* fix: address code review feedback (attempt 1/5)

- M1: Round quotaPercent display with Math.round() to avoid ugly floats
- M2: Rename exhaust_threshold -> exhaustion_threshold for consistency
  with existing auto.exhaustion_threshold config field
- M3: Replace async not.toThrow() with direct await assertion pattern

* fix: address code review feedback (attempt 2/5)

- Remove .claude/agent-memory/ from tracking and add to .gitignore
- Unify cooldown_minutes default to 5 (was 10 in runtime_monitor, 5 in auto)
- Add threshold validation in startQuotaMonitor (warn > exhaustion)
- Document intentional post-switch monitoring gap in code comment

* chore(release): 7.41.0-dev.4 [skip ci]

* fix(cliproxy): mask email in ban detection and fix JSDoc default

- Use maskEmail() in handleBanDetection output for consistency
- Fix cooldown_minutes JSDoc: default is 5, not 10

* chore(release): 7.41.0-dev.5 [skip ci]

* fix(cliproxy): address all review feedback (Low + informational)

- Add sync constraint comment on process.exit handler (executor)
- Add TOCTOU race acceptability comment (account-safety)
- Mask email in handleQuotaExhaustion reason string
- Use realistic exhaustion_threshold (5) in test configs

* chore(release): 7.41.0-dev.6 [skip ci]

Date: Thu, 12 Feb 2026 01:23:29 +0700
Subject: [PATCH 170/658] fix(cursor): address second-round review feedback for
 auth module

- Add comprehensive unit tests for cursor-auth.test.ts
  - validateToken: valid/invalid tokens, short tokens, UUID formats, empty strings
  - extractUserInfo: JWT parsing, email handling, non-JWT tokens, malformed base64
  - saveCredentials/loadCredentials: round-trip, invalid JSON/types, missing fields
  - checkAuthStatus: authenticated/not authenticated, expired tokens, JWT exp, invalid dates
  - deleteCredentials: delete existing/non-existent files, multiple deletes
  - All tests use CCS_HOME env var for isolation, real file I/O, no mocks

- Fix dead try-catch around new Date() in checkAuthStatus()
  - Replace try-catch with isNaN check (new Date('garbage') returns Invalid Date, not throw)
  - Properly handle Invalid Date by checking isNaN(getTime())

- Fix email populated with sub claim in extractUserInfo()
  - Change email: decoded.email || decoded.sub to email: decoded.email || undefined
  - Prevent non-email values (UUIDs) from populating email field

- Add type guards for JSON.parse result in extractUserInfo()
  - Cast to Record<string, unknown> and validate types
  - Use typeof checks for email, userId, exp fields

Subject: [PATCH 171/658] fix(cursor): address second-round review feedback for
 protobuf module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HIGH Priority:
- Add comprehensive unit tests (27 tests covering encoder, decoder, translator, executor)
  * encodeVarint/decodeVarint round-trip (0, 1, 127, 128, 16383, 0xFFFFFFFF)
  * encodeField/decodeField round-trip (VARINT, LEN string, LEN binary)
  * wrapConnectRPCFrame/parseConnectRPCFrame (compressed/uncompressed)
  * buildCursorRequest message translation (system, user, assistant, tool)
  * generateChecksum header format validation
  * buildHeaders output validation
  * transformProtobufToJSON basic conversion
- Create GitHub issue #531 for true streaming implementation
- Update TODO comment to reference issue #531

MEDIUM Priority:
- Export CursorCredentials from cursor-protobuf-schema.ts
- Add JSDoc grouping comments to FIELD constant for clarity
- Make hardcoded values configurable (CURSOR_CLIENT_VERSION, CURSOR_USER_AGENT)
- Add debug logging to 9 silent catch blocks (respects CCS_DEBUG env var)
- Fix stream check: stream !== false → stream === true

Bug Fixes:
- Fix decodeVarint to return unsigned values (>>> 0)
- Fix test assertion for Response.text() async API

Subject: [PATCH 172/658] feat(glm): update default model to GLM-5 and fix all
 GLM pricing

- Update default GLM model from glm-4.7 to glm-5 across configs, presets, help text, and fallbacks
- Add glm-5 pricing entry ($1.00/$3.20 per M tokens, OpenRouter verified)
- Fix incorrect glm-4.7 pricing: $0.60/$2.20 -> $0.40/$1.50 (OpenRouter verified)
- Fix incorrect glm-4.6 pricing: $0.60/$2.20 -> $0.35/$1.50 (OpenRouter verified)
- Fix incorrect glm-4.5 pricing: $0.60/$2.20 -> $0.35/$1.55 (OpenRouter verified)
- Keep all previous GLM model entries for backward compatibility

Closes #532

Subject: [PATCH 177/658] fix(cursor): address third-round review feedback for
 protobuf module

HIGH PRIORITY FIXES:
- Extract shared buffer parsing logic into parseProtobufFrames generator
  method (DRY violation fix) - both JSON and SSE transformers now use
  common frame parsing loop, eliminating ~60% code duplication
- Use COMPRESS_FLAG constants instead of hardcoded 0x01/0x02/0x03 in
  parseConnectRPCFrame for better maintainability

MEDIUM PRIORITY FIXES:
- Return empty buffer on gzip decompression failure (prevents silent
  data corruption) - ALREADY FIXED
- Add debug warning for unknown message roles in convertMessages
- Create GitHub issue #535 for FIELD namespace refactoring follow-up
- Add test coverage: transformProtobufToSSE, error paths, unknown roles

LOW PRIORITY FIXES:
- Rename checksum test to clarify timestamp granularity (~16 min)
- Fix debug log function name in SSE transformer - FIXED BY REFACTOR
- Add comment to TOOL_RESULT_RESULT field documenting future use

All tests pass (1593 pass, 0 fail)
All validation checks pass (typecheck + lint + format + tests)

Subject: [PATCH 180/658] fix(cursor): tighten rate limit detection string
 matching

Use specific patterns ('rate limit', 'resource_exhausted', 'too many
requests') instead of broad 'rate' or 'limit' substrings that would
false-positive on unrelated errors like 'character limit exceeded'.

Subject: [PATCH 183/658] fix(cursor): address PR #527 review feedback

- Wire cursor command into main router (ccs.ts) following copilot pattern
- Centralize default port (4242) and model (gpt-4.1) as constants
- Remove duplicate types already in cursor-protobuf-schema from dev
- Handle daemon exit code 0 before health check succeeds
- Export PID helpers and model utils for testability
- Add unit tests for cursor-daemon (PID file ops, isDaemonRunning)
- Add unit tests for cursor-models (detectProvider, formatModelName, defaults)

- Add getCompositeEnvVars() for root URL + per-tier model env vars
- Extend ProxyChainConfig with composite fields
- Route composite variants through root URL in buildClaudeEnvironment()
- Multi-provider auth check for composite (all tiers must pass)
- Multi-provider token refresh for composite
- Per-tier broken model check
- Block --config for composite variants
- Pass composite config through to env resolver

Subject: [PATCH 188/658] feat(cliproxy): add composite variant CLI wizard

- Add --composite flag to 'ccs cliproxy variant create'
- Implement selectTierConfig() interactive prompt per tier
- Add default tier selection after all tiers configured
- Display composite label in auth list and variant remove
- Show per-tier details in remove confirmation
- Update help text with --composite usage

Subject: [PATCH 189/658] feat(cliproxy): wire composite variant into main
 execution flow

- Detect composite variants in ProfileDetector with tier metadata
- Pass isComposite/compositeTiers/compositeDefaultTier through ccs.ts
- Handle composite in loadConfigSafe() legacy adapter
- Add validateCompositeVariants() for provider string validation
- Display 'composite' label in API profile listing

Subject: [PATCH 193/658] fix(cursor): address remaining PR #528 review
 feedback

- Add comment explaining whitelist merge pattern in PUT /settings
- Add comment for bare 'ccs cursor' fallthrough (differs from copilot)
- Add unit tests for cursor settings routes validation logic
  - Tests for null/non-object/array body rejection
  - Tests for port validation (integer, range 1-65535)
  - Tests for auto_start/ghost_mode boolean validation
  - Tests for whitelist merge (ignores unknown properties)
  - Tests for /settings/raw validation and file operations
  - Tests for mtime conflict detection

All web-server tests pass. Pre-existing test failures unrelated.

Subject: [PATCH 195/658] feat(cliproxy): add provider error detection for
 composite fallback

- Add PROVIDER_ERROR_PATTERNS for HTTP 4xx/5xx, overloaded, quota, rate limit
- Add detectFailedTier() to identify which composite tier failed from stderr
- Add isProviderError() to distinguish provider failures from normal exits

Subject: [PATCH 198/658] fix(cursor): add resolve guard, port validation, and
 daemon tests

- Add double-resolve guard in startDaemon with safeResolve wrapper
- Add port validation (1-65535) before Node.js script interpolation
- Fix misleading comment in stopDaemon (no PID file handling)
- Add getDaemonStatus test for no daemon running case
- Add stopDaemon tests for graceful non-existent PID handling

Subject: [PATCH 200/658] fix(cursor): kill orphaned daemon on timeout and fix
 exit codes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MEDIUM fixes:
- Kill orphaned process when health check times out after 30s
- Prevents zombie processes from consuming resources

LOW fixes:
- Return exit code 1 for unknown cursor subcommands (was 0)
- Simplify exit handler dead code branch (else if code !== null → else)

Subject: [PATCH 207/658] fix(cursor): align daemon routes, add enabled field,
 handle bare command

- Change /start and /stop to /daemon/start and /daemon/stop matching copilot convention
- Add enabled field to CursorConfig for dashboard toggle parity
- Simplify getCursorConfig() to trust mergeWithDefaults()
- Handle bare 'ccs cursor' to show help instead of reserved-name error

 and improve daemon robustness

- Add removePidFile() in safeResolve on failure to prevent stale PIDs
- Only send SIGKILL in stopDaemon if SIGTERM wait loop exhausted
- Check isDaemonRunning before model fetch to avoid 5s timeout
- Add port validation unit tests for startDaemon

Subject: [PATCH 229/658] fix(cliproxy): address 3 functional regressions in
 composite variants

P1 (Critical): Remote composite execution now correctly uses remote endpoint
- Reorder condition to check useRemoteProxy before isComposite
- Composite variants now work with remote CLIProxy instances

P2a (Medium): Tier deep-merge preserves optional fields during updates
- Use spread merge instead of ?? to preserve fallback/thinking/account

P2b (Medium): API accepts partial tier updates in PUT endpoint
- Skip validation for tiers not present in request
- Aligns with updateCompositeVariant's merge behavior

 composite variants

- P1: Remote composite env now uses remote endpoint/auth
  Add CompositeRemoteConfig parameter to getCompositeEnvVars()
  Pass remote config when useRemoteProxy is true

- P2: Tier thinking uses tier-specific provider
  Extract tier provider from compositeTiers for supportsThinking()
  Fix mixed-provider composite thinking config

- P2: Force variant removal checks result
  Fail fast if removeVariant fails in --force mode

- P2: Guard composite validation against missing tiers
  Add null check before Object.entries(variant.tiers)

Subject: [PATCH 234/658] fix(cliproxy): address 3 code review issues in
 composite variants

- P1: Remove premature variant deletion in --force mode
  Fix destructive overwrite path - old variant preserved if user
  cancels auth or creation fails (createVariant handles overwrite)

- P2: Validate all composite tier providers at runtime
  Backend gating now checks all providers in composite, not just
  default tier. Prevents kiro/ghcp on non-default tiers bypassing
  Plus backend requirement.

- P2: Preserve tier thinking when default tier is off
  Early return skipped tier processing when default thinking was
  "off". Now uses flag-based approach - only main model skipped,
  tier loop continues with per-tier thinking config.

Subject: [PATCH 235/658] fix(cliproxy): fix edit dialog empty model and
 composite guidance

- P2: Edit dialog no longer seeds empty model string
  Changed `variant.model || ''` to `variant.model ?? undefined`
  Added payload filtering to exclude undefined/empty values before API call
  Prevents unintended model overwrites when user only changes other fields

- P3: Composite --config guidance now uses variant name
  Added profileName to ExecutorConfig interface
  Error message now shows correct variant name instead of default tier provider
  e.g., "ccs cliproxy edit my-mix" instead of "ccs cliproxy edit gemini"

+# Hardening Debt Burndown Tracker
+
+Last Updated: 2026-02-12
+Owner: Stream D (`#542`)
+
+## Scope
+
+Maintainability hardening groundwork with low-risk changes:
+
+- Inventory legacy shims/compatibility markers
+- Inventory sync filesystem usage, especially runtime hotpaths
+- Incrementally migrate hotpath sync I/O to async I/O with tests
+
+## How to Measure
+
+Run:
+
+```bash
+bun run report:hardening
+```
+
+Generated artifacts:
+
+- `docs/reports/hardening-inventory.json`
+- `docs/reports/hardening-inventory.md`
+
+## Kickoff Baseline (Issue #542 Stream D)
+
+The current baseline is sourced from `docs/reports/hardening-inventory.json` after running `bun run report:hardening`.
+Baseline captured: `2026-02-12`.
+
+| Metric | Baseline |
+|---|---:|
+| Sync fs occurrences (all) | 841 |
+| Sync fs files affected (all) | 100 |
+| Sync fs occurrences (runtime hotpaths) | 730 |
+| Sync fs files affected (runtime hotpaths) | 89 |
+| Legacy shim markers | 131 |
+| Legacy shim files affected | 56 |
+
+## Initial Async I/O Migration Log
+
+| Date | Area | Change | Safety Notes |
+|---|---|---|---|
+| 2026-02-12 | `src/web-server/jsonl-parser.ts` | Migrated `parseProjectDirectory()` directory listing from sync `readdirSync` to async `fs.promises.readdir` | Existing behavior kept (same filtering/fallback); covered by `tests/unit/jsonl-parser.test.ts` |

Subject: [PATCH 240/658] fix(cliproxy): fix thinking off regression and
 composite error handling

- P1: Thinking "off" now fully disables all tier thinking
  When thinkingValue === 'off' AND no per-tier config, return early
  Preserves behavior for "off" with per-tier config (skips main, processes tiers)
  Fixes regression where tier defaults were applied despite explicit off setting

- P2: Handle composite-create thrown errors in POST route
  Wrap createCompositeVariant() in try/catch
  Returns 400 instead of generic 500 when function throws (e.g., legacy mode)

Subject: [PATCH 258/658] fix(cursor): close ReadableStream controller on abort
 to prevent consumer hangs

When abort fires after streaming begins, onAbort closed HTTP/2 handles
but never closed the ReadableStream controller. Consumers waiting on
reader.read() could hang indefinitely since end/error handlers were
gated by streamClosed flag.

Hoist controller reference to outer scope so abort handler can close it.

Subject: [PATCH 261/658] fix(cliproxy): keep variant updates atomic and
 persisted

- require model when changing single-variant provider to avoid mixed config

- rewrite provider-specific core env when provider changes while preserving custom fields

- preserve custom composite settings path and return persisted composite PUT state

Subject: [PATCH 270/658] fix(cliproxy): mark Kiro as device_code flow for
 dashboard auth

CLIProxyAPIPlus uses device code flow for Kiro authentication, returning
{method: "device_code", state, status} without an immediate URL. The URL
is provided via polling the /get-auth-status endpoint.

Previously, Kiro was configured as authorization_code flow, causing
dashboard auth to fail with "No authorization URL received from CLIProxyAPI"
because the web-server routes expected synchronous URL response.

Changes:
- provider-capabilities.ts: kiro.oauthFlow = 'device_code', callbackPort = null
- provider-config.ts: Add 'kiro' to DEVICE_CODE_PROVIDERS array
- provider-capabilities.test.ts: Update test expectations

This routes Kiro through /start endpoint which properly handles device code
flow via WebSocket events (deviceCodeReceived, deviceCodeCompleted, etc).

Closes #552

+# Cursor IDE Integration
+
+This guide covers the local Cursor integration in CCS, including CLI setup, daemon lifecycle, and dashboard controls.
+
+## What It Provides
+
+- OpenAI-compatible local endpoint powered by Cursor credentials.
+- Cursor model list and chat completions via local daemon.
+- Dedicated dashboard page: `ccs config` -> `Cursor IDE`.
+
+## Prerequisites
+
+- Cursor IDE installed and logged in.
+- CCS installed and configured (`ccs config` works).
+- For auto-detect auth on macOS/Linux: `sqlite3` available in PATH.
+
+## CLI Workflow
+
+### 1) Enable integration
+
+```bash
+ccs cursor enable
+```
+
+### 2) Import credentials
+
+Auto-detect from Cursor local SQLite state:
+
+```bash
+ccs cursor auth
+```
+
+Manual fallback:
+
+```bash
+ccs cursor auth --manual --token <token> --machine-id <machine-id>
+```
+
+### 3) Start daemon
+
+```bash
+ccs cursor start
+```
+
+### 4) Verify status
+
+```bash
+ccs cursor status
+```
+
+### 5) Stop daemon
+
+```bash
+ccs cursor stop
+```
+
+## Runtime Defaults
+
+- Default port: `20129`
+- `ghost_mode`: enabled
+- `auto_start`: disabled
+
+These values are managed in unified config and can be updated from CLI or dashboard.
+
+## Dashboard Usage
+
+Open dashboard:
+
+```bash
+ccs config
+```
+
+Then navigate to `Cursor IDE` in the sidebar.
+
+Available controls:
+
+- Integration toggle (`enabled`)
+- Auth actions (auto-detect, manual import)
+- Daemon actions (start/stop)
+- Runtime config (port, auto-start, ghost mode)
+- Models list
+- Raw editor for `~/.ccs/cursor.settings.json`
+
+## Raw Settings and Unified Config Sync
+
+Raw settings are stored in:
+
+`~/.ccs/cursor.settings.json`
+
+When raw settings include a local `ANTHROPIC_BASE_URL` port override, CCS synchronizes that port back into unified config so CLI and dashboard remain consistent.
+
+## Troubleshooting

+### Auto-detect fails
+
+- Ensure Cursor is logged in.
+- Confirm `sqlite3` is installed (macOS/Linux).
+- Use manual auth import if needed.

+- Check if port `20129` is in use.
+- Change port in dashboard config tab, then retry `ccs cursor start`.

Subject: [PATCH 306/658] fix(web-server): make kiro auth routes method-aware

- validate kiroMethod on /start and /start-url with clear errors

- route Kiro management start-url requests with upstream method query

- accept state-first responses and keep auth_url optional

- add start-url guard tests for Kiro social and aws-authcode paths

Subject: [PATCH 312/658] feat(cursor): sync model mapping across config and
 raw settings

- add cursor model fields to unified config defaults and YAML comments

- expand Cursor model catalog/defaults and return configured current model

- keep cursor.settings.json env model fields in sync with config updates

- align unit tests for new model defaults and route merge behavior

Subject: [PATCH 322/658] feat(targets): add multi-target CLI adapter system
 (Droid support)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement target adapter pattern enabling CCS CLI to support multiple backend targets
(Claude, Droid) via pluggable adapters. Core additions:

- TargetAdapter interface for pluggable target implementations
- ClaudeAdapter and DroidAdapter concrete implementations
- Target registry (singleton Map-based storage)
- Target resolver with precedence: --target flag > per-profile config > busybox detection
- Droid config manager with atomic writes and file locking to ~/.factory/settings.json
- Droid binary detector to validate runtime environment
- Adapter dispatch integrated into ccs.ts main execution flow
- ccsd busybox alias for seamless Droid invocation
- --target flag documentation in help
- Session tracking enriched with target metadata
- Dashboard target badge for visual identification

Testing:
- 43 unit tests covering resolver, registry, config manager, and adapters
- Full coverage of target detection logic and edge cases

Documentation:
- Refactored system-architecture.md into modular docs/system-architecture/ subdirectory
- Updated code-standards.md with target adapter guidelines
- Updated codebase-summary.md with architecture overview
- Updated maintainability baseline (33.8% → 35.2%)

This establishes extensible foundation for multi-target support without breaking
existing Claude workflows. Droid adapter is production-ready but defaults to Claude
for backward compatibility.

+## Target Adapter Pattern
+
+The target adapter pattern enables pluggable support for multiple CLI implementations (Claude Code, Factory Droid, etc.) while preserving a unified profile system.
+
+### Pattern Overview
+
+**Each CLI target implements a `TargetAdapter` interface:**
+
+```typescript
+interface TargetAdapter {
+  readonly type: TargetType;                                    // 'claude' | 'droid'
+  readonly displayName: string;                                 // Human-readable name
+
+  detectBinary(): TargetBinaryInfo | null;                      // Find CLI on system
+  prepareCredentials(creds: TargetCredentials): Promise<void>;  // Deliver credentials
+  buildArgs(profile: string, userArgs: string[]): string[];    // Build CLI args
+  buildEnv(creds: TargetCredentials, type: string): Env;       // Build env vars
+  exec(args: string[], env: Env): void;                        // Spawn CLI process
+  supportsProfileType(type: string): boolean;                  // Validate profile
+}
+```
+
+### Key Differences Per Target
+
+| Aspect | Claude | Droid |
+|--------|--------|-------|
+| **Credential delivery** | Environment variables | Config file (~/.factory/settings.json) |
+| **Spawn args** | `claude <args>` | `droid -m custom:ccs-<profile> <args>` |
+| **Config write** | None (uses env) | `upsertCcsModel()` writes to settings |
+| **Binary detection** | `detectClaudeCli()` | `detectDroidCli()` with version check |
+
+### Target Resolution Priority
+
+Resolves which adapter to use via `resolveTargetType()`:
+
+```
+1. --target <name> flag (highest priority)
+   ↓
+2. Profile config: profileConfig.target field
+   ↓
+3. argv[0] detection (busybox pattern):
+   - ccsd → droid
+   - ccs → default
+   ↓
+4. Fallback: 'claude' (lowest priority)
+```
+
+### Registration Pattern
+
+At startup, adapters self-register into the runtime registry:
+
+```typescript
+// In ccs.ts or initialization
+registerTarget(new ClaudeAdapter());
+registerTarget(new DroidAdapter());
+
+// Later, when executing
+const targetType = resolveTargetType(args, profileConfig);
+const adapter = getTarget(targetType);
+
+await adapter.prepareCredentials(credentials);
+const spawnArgs = adapter.buildArgs(profile, userArgs);
+adapter.exec(spawnArgs, adapter.buildEnv(credentials, profileType));
+```
+
+### Adding a New Target
+
+To add support for a new CLI (e.g., `newcli`):
+
+1. Create `src/targets/newcli-adapter.ts` implementing `TargetAdapter`
+2. Implement each required method (detection, credential delivery, spawning)
+3. Create `src/targets/newcli-detector.ts` for binary detection logic
+4. Export from `src/targets/index.ts`
+5. Register in `ccs.ts`: `registerTarget(new NewCliAdapter())`
+6. Update `TargetType` union to include `'newcli'`

 ```
 
+### Cross-Platform Adapter Spawning
+
+When implementing target adapters, handle platform differences for binary spawning:
+
+```typescript
+// Window shell detection (.cmd, .bat, .ps1 require shell)
+const needsShell = isWindows && /\.(cmd|bat|ps1)$/i.test(binaryPath);
+
+if (needsShell) {
+  // Escape arguments and use shell: true
+  const cmdString = [binaryPath, ...args].map(escapeShellArg).join(' ');
+  spawn(cmdString, { shell: true, stdio: 'inherit' });
+} else {
+  // Direct spawn (Unix-like, unshelled Windows executables)
+  spawn(binaryPath, args, { stdio: 'inherit' });
+}
+```
+
+This pattern is used in both `ClaudeAdapter` and `DroidAdapter` to ensure cross-platform consistency.

+### Target Adapter Module
+
+The targets module provides an extensible interface for dispatching profiles to different CLI implementations.
+
+**Key components:**
+
+1. **TargetAdapter Interface** - Contract that each CLI implementation must fulfill:
+   - `detectBinary()` - Find CLI binary on system (platform-specific)
+   - `prepareCredentials()` - Deliver credentials (env vars vs config file writes)
+   - `buildArgs()` - Construct target-specific argument list
+   - `buildEnv()` - Construct environment for target CLI
+   - `exec()` - Spawn target process (cross-platform)
+   - `supportsProfileType()` - Verify profile compatibility
+
+2. **Target Resolution** - Priority order:
+   - `--target <cli>` flag (CLI argument)
+   - Per-profile `target` field (from config.yaml)
+   - `argv[0]` detection (busybox pattern: `ccsd` → droid)
+   - Default: `claude`
+
+3. **Implementations:**
+   - **ClaudeAdapter** - Wraps existing behavior; delivers credentials via environment variables
+   - **DroidAdapter** - New; writes to ~/.factory/settings.json and spawns with `-m custom:ccs-<profile>` flag
+
+4. **Registry** - Map-based lookup (O(1)) for registered adapters at runtime
+
+**Usage flow:**
+```
+Profile resolution (existing)
+  ↓
+Target resolution (via resolver.ts)
+  ↓
+Get adapter from registry
+  ↓
+Prepare credentials (adapter.prepareCredentials)
+  ↓
+Build args & env (adapter.buildArgs, buildEnv)
+  ↓
+Spawn target CLI (adapter.exec)
+```

-# CCS System Architecture
-
-Last Updated: 2026-02-04
-
-High-level architecture documentation for the CCS (Claude Code Switch) system.
-
----
-
-## System Overview
-
-CCS is a CLI wrapper that enables seamless switching between multiple Claude accounts and alternative AI providers (GLM, Gemini, Codex, Kiro, GitHub Copilot, OpenRouter, Qwen, Kimi, DeepSeek). It consists of two main components:
-
-1. **CLI Application** (`src/`) - Node.js TypeScript CLI
-2. **Dashboard UI** (`ui/`) - React web application served by Express
-
-CCS v7.34 adds Image Analysis Hook for vision model proxying through CLIProxy with automatic injection for all profile types.

-
-  OAuth Providers - Authorization Code Flow (Gemini, Codex, AGY)
-  --------------------------------------------------------------
-
-  1. User runs: ccs gemini
-        |
-        v
-  2. Check token cache (~/.ccs/cliproxy/auth/)
-        |
-        +---> [Valid token] ---> Use cached token
-        |
-        +---> [No/Expired token]
-                    |
-                    v
-  3. Open browser for OAuth (localhost:PORT callback)
-        v
-  4. Callback with auth code
-        |
-        v
-  5. Exchange for access token
-        |
-        v
-  6. Cache token locally
-
-
-  Kiro OAuth - Method-Aware Flow (CLI + Dashboard parity)
-  -------------------------------------------------------
-
-  Supported methods:
-    - aws: Device Code (default, AWS org friendly)
-    - aws-authcode: Authorization Code via CLI flow
-    - google: Social OAuth via management API
-    - github: Social OAuth via management API (Dashboard flow)
-
-  Key behavior:
-    - Device Code method uses /start route (no callback port)
-    - Callback/social methods use /start-url + status polling
-    - Some management flows return state first, auth_url later
-
-
-  OAuth Providers - Device Code Flow (GitHub Copilot/ghcp)
-  --------------------------------------------------------
-
-  1. User runs: ccs ghcp
-        |
-        v
-  2. Check token cache (~/.ccs/cliproxy/auth/)
-        |
-        +---> [Valid token] ---> Use cached token
-        |
-        +---> [No/Expired token]
-                    |
-                    v
-  3. Request device code from GitHub
-        |
-        v
-  4. Display user code + verification URL
-        |     "Enter code XXXX-XXXX at github.com/login/device"
-        v
-  5. Poll for token (user completes auth in browser)
-        |
-        v
-  6. Receive and cache token locally
-
-
-  API Key Profiles (GLM, Kimi)
-  ----------------------------
-
-  1. User configures API key in settings
-        |
-        v
-  2. Key stored in ~/.ccs/<profile>.settings.json
-        |
-        v
-  3. Key passed via ANTHROPIC_AUTH_TOKEN env var

+# CCS System Architecture
+
+Last Updated: 2026-02-16
+
+High-level architecture overview for the CCS (Claude Code Switch) system.
+
+---
+
+## System Overview
+
+CCS is a CLI wrapper that enables seamless switching between multiple Claude accounts and alternative AI providers (GLM, Gemini, Codex, Kiro, GitHub Copilot, OpenRouter, Qwen, Kimi, DeepSeek). It now supports multiple CLI targets (Claude Code, Factory Droid) for credential delivery.
+
+The system consists of two main components:
+
+1. **CLI Application** (`src/`) - Node.js TypeScript CLI
+2. **Dashboard UI** (`ui/`) - React web application served by Express
+
+CCS v7.34 adds Image Analysis Hook for vision model proxying through CLIProxy with automatic injection for all profile types.
+

+## Component Architecture
+
+### Multi-Target Adapter System
+
+CCS v7.45 introduces the Target Adapter pattern, enabling seamless integration with different CLI implementations.
+
+**Key architecture:**
+
+```
+Profile Resolution (CLIProxy, GLMT, Account-based)
+        |
+        v
+Target Resolution (--target flag > config > argv[0] > default)
+        |
+        v
+Get Target Adapter (Claude or Droid)
+        |
+        +---> detectBinary()     (find CLI on system)
+        |
+        +---> prepareCredentials() (write config or set env)
+        |
+        +---> buildArgs()        (construct CLI arguments)
+        |
+        +---> buildEnv()         (prepare environment variables)
+        |
+        v
+Spawn Target Process
+```
+
+**Each target adapter implements different credential delivery:**
+
+- **Claude Adapter**: Env var delivery (existing behavior)
+  - `ANTHROPIC_BASE_URL`, `ANTHROPIC_AUTH_TOKEN`, `ANTHROPIC_MODEL`
+  - No config files needed
+
+- **Droid Adapter**: Config file delivery to `~/.factory/settings.json`
+  - Writes custom model entry: `custom:ccs-<profile>`
+  - Spawns: `droid -m custom:ccs-<profile> <args>`
+  - Model config includes baseUrl, apiKey, provider
+
+**Binary alias pattern (busybox-style):**
+
+```
+ccs  → Target: claude (default)
+ccsd → Target: droid (auto-selected via argv[0])
+```
+
+For details on the adapter architecture, see [Target Adapters](./target-adapters.md).

+### Supported Hardcoded Providers
+
+| Provider | ID | Auth Method | Port | Binary |
+|----------|----|----|------|--------|
+| Gemini | `gemini` | Authorization Code | 9876 | CLIProxyAPI |
+| Codex | `codex` | Authorization Code | 9876 | CLIProxyAPI |
+| Antigravity | `agy` | Authorization Code | 9876 | CLIProxyAPI |
+| Kiro (AWS) | `kiro` | Method-aware (default: Device Code) | 9876 | CLIProxyAPIPlus |
+| GitHub Copilot | `ghcp` | Device Code | none | CLIProxyAPIPlus |
+
+### Hardcoded Provider Detection
+
+CCS detects hardcoded providers via `profile-detector.ts` and routes through `execClaudeWithCLIProxy()`.
+
+```typescript
+// Profile name matching
+const hardcodedProviders = ['gemini', 'codex', 'agy', 'kiro', 'ghcp'];
+
+if (hardcodedProviders.includes(profileName)) {
+  return execClaudeWithCLIProxy(claudeCli, profileName, args);

+| Z.AI (GLM) | `glmt` | https://open.bigmodel.cn/api/paas/v4/ | API key |
+| Kimi | `kimi` | https://api.moonshot.cn/v1/ | API key |
+| OpenRouter | `openrouter` | https://openrouter.ai/api/v1/ | API key |
+
+### GLMT Profile Detection
+
+CCS detects GLMT profiles and routes through `execClaudeWithProxy()`:
+
+```typescript
+// Settings-based profile detection
+const settings = loadSettings(profileName);
+if (settings.env?.ANTHROPIC_BASE_URL?.includes('glm') ||
+    settings.env?.ANTHROPIC_BASE_URL?.includes('moonshot') ||
+    settings.env?.ANTHROPIC_BASE_URL?.includes('openrouter')) {
+  return execClaudeWithProxy(claudeCli, profileName, args);
+}
+```

+
+## Remote CLIProxy Flow (v7.1)
+
+### Overview
+
+Remote CLIProxy enables CCS to delegate authentication to a central proxy server instead of spawning a local binary.

+      → Poll /status for completion
+
+  Key behavior:
+    - Device Code method uses /start route (no callback port)
+    - Callback/social methods use /start-url + status polling

+## Session Tracking
+
+All execution paths record session metadata including target CLI used:
+
+```typescript
+{
+  profileName: 'gemini',
+  profileType: 'clipproxy',
+  provider: 'google-gemini',
+  targetCli: 'claude',        // NEW: which target was used
+  timestamp: '2026-02-16T10:40:00Z',
+  duration: 12345,
+  exitCode: 0,
+  model: 'claude-opus-4-6',
+}
+```
+
+This enables analytics on target CLI usage and adoption.

+# Target Adapters
+
+Last Updated: 2026-02-16
+
+Detailed documentation of the target adapter pattern and implementations.
+
+---
+
+## Overview
+
+The target adapter system enables CCS to dispatch credential-resolved profiles to different CLI implementations while maintaining a unified configuration and profile system.
+
+**Key insight**: Profile resolution (detecting provider, loading auth, building credentials) is target-agnostic. Only the final credential delivery and process spawning differ per target.
+
+---
+
+## Target Adapter Interface
+
+Each CLI target implements the `TargetAdapter` contract:
+
+```typescript
+export interface TargetAdapter {
+  readonly type: TargetType;                               // 'claude' | 'droid'
+  readonly displayName: string;                            // "Claude Code" | "Factory Droid"
+
+  /** Detect if the target CLI binary exists on system */
+  detectBinary(): TargetBinaryInfo | null;
+
+  /** Prepare credentials for delivery to target CLI */
+  prepareCredentials(creds: TargetCredentials): Promise<void>;
+
+  /** Build spawn arguments for the target CLI */
+  buildArgs(profile: string, userArgs: string[]): string[];
+
+  /** Build environment variables for the target CLI */
+  buildEnv(creds: TargetCredentials, profileType: string): NodeJS.ProcessEnv;
+
+  /** Spawn the target CLI process (replaces current process flow) */
+  exec(args: string[], env: NodeJS.ProcessEnv, options?: { cwd?: string }): void;
+
+  /** Check if a profile type is supported by this target */
+  supportsProfileType(profileType: string): boolean;
+}
+```
+
+### Type Definitions
+
+```typescript
+export type TargetType = 'claude' | 'droid';
+
+export interface TargetCredentials {
+  baseUrl: string;                                         // API endpoint
+  apiKey: string;                                          // Auth token
+  model?: string;                                          // Model ID
+  provider?: 'anthropic' | 'openai' | 'generic-chat-completion-api';
+  envVars?: NodeJS.ProcessEnv;                             // Additional env vars
+}
+
+export interface TargetBinaryInfo {
+  path: string;                                            // Full path to binary
+  needsShell: boolean;                                     // Windows .cmd/.bat/.ps1?
+}
+```
+
+---
+
+## Target Resolution
+
+CCS resolves which adapter to use via priority-ordered checks:
+
+### Resolution Priority
+
+```
+1. --target flag (CLI argument) — highest priority
+   └─ ccs --target droid glm
+
+2. Per-profile config (from ~/.ccs/config.yaml or settings.json)
+   └─ profiles:
+        glm:
+          target: droid
+
+3. argv[0] detection (busybox pattern) — binary name mapping
+   └─ ccsd (symlink/batch file) → droid
+   └─ ccs (regular command) → default
+
+4. Fallback: 'claude' — lowest priority
+```
+
+### Implementation
+
+```typescript
+// src/targets/target-resolver.ts
+
+export function resolveTargetType(
+  args: string[],
+  profileConfig?: { target?: TargetType }
+): TargetType {
+  // 1. Check --target flag
+  const targetIdx = args.indexOf('--target');
+  if (targetIdx !== -1 && args[targetIdx + 1]) {
+    const flagValue = args[targetIdx + 1];
+    if (VALID_TARGETS.has(flagValue)) {
+      return flagValue as TargetType;
+    }
+    // Invalid target → error
+    console.error(`[X] Unknown target "${flagValue}". Available: claude, droid`);
+    process.exit(1);
+  }
+
+  // 2. Check profile config
+  if (profileConfig?.target) {
+    return profileConfig.target;
+  }
+
+  // 3. Check argv[0] (binary name)
+  const binName = path.basename(process.argv[1] || '').replace(/\.(cmd|bat)$/i, '');

+
+  supportsProfileType(profileType: string): boolean {
+    // Droid supports all profile types (like Claude)
+    return true;
+  }
+}
+```
+
+### Credential Delivery
+
+**Method**: Config file (`~/.factory/settings.json`)
+
+```json
+{
+  "customModels": {
+    "ccs-gemini": {
+      "model": "claude-opus-4-6",
+      "displayName": "CCS gemini",
+      "baseUrl": "https://generativelanguage.googleapis.com/v1beta/openai/",

+ln -s /path/to/ccs /path/to/ccsd
+
+# Usage
+ccsd glm
+→ Target: droid (detected from argv[0])
+→ droid -m custom:ccs-glm "args..."
+```
+
+---
+
+## Registry and Lookup
+
+The target registry is a simple map-based store for adapters:
+
+```typescript
+// src/targets/target-registry.ts
+
+const adapters = new Map<TargetType, TargetAdapter>();
+
+export function registerTarget(adapter: TargetAdapter): void {
+  adapters.set(adapter.type, adapter);
+}
+
+export function getTarget(type: TargetType): TargetAdapter {
+  const adapter = adapters.get(type);
+  if (!adapter) {
+    throw new Error(`Unknown target "${type}"`);
+  }
+  return adapter;
+}
+
+export function getDefaultTarget(): TargetAdapter {
+  return getTarget('claude');
+}
+```
+
+### Adapter Registration
+
+At startup, adapters self-register:
+
+```typescript
+// src/ccs.ts (initialization)
+
+registerTarget(new ClaudeAdapter());
+registerTarget(new DroidAdapter());
+```
+
+---
+
+## Execution Flow
+
+### Step-by-Step
+
+```
+1. Parse command-line arguments
+   └─ args: ['--target', 'droid', 'glm']
+
+2. Resolve target type
+   └─ resolveTargetType(args) → 'droid'
+   └─ stripTargetFlag(args) → ['glm']
+
+3. Detect and resolve profile
+   └─ detectProfile(['glm']) → { profile: 'glm', ... }
+   └─ Load credentials from config/CLIProxy/env
+
+4. Build credentials object
+   └─ TargetCredentials {
+        baseUrl: '...',
+        apiKey: '...',
+        model: 'claude-opus-4-6',
+        envVars: { CCS_PROFILE_NAME: 'glm', ... }
+      }
+
+5. Get target adapter
+   └─ getTarget('droid') → DroidAdapter instance
+
+6. Prepare credentials
+   └─ adapter.prepareCredentials(creds)
+   └─ DroidAdapter: writes to ~/.factory/settings.json
+
+7. Build spawn arguments
+   └─ adapter.buildArgs('glm', []) → ['-m', 'custom:ccs-glm']
+
+8. Build environment
+   └─ adapter.buildEnv(creds, profileType) → process.env
+
+9. Spawn target CLI
+   └─ adapter.exec(spawnArgs, env)
+   └─ exec spawn('droid', ['-m', 'custom:ccs-glm', ...])
+
+10. Replace current process
+    └─ Child process inherits stdio
+    └─ Signal handlers propagate to child
+```
+
+---
+
+## Adding a New Target
+
+To support a new CLI (e.g., MyAI CLI), follow this pattern:
+
+### 1. Create Adapter Class
+
+```typescript
+// src/targets/myai-adapter.ts
+
+export class MyAiAdapter implements TargetAdapter {
+  readonly type: TargetType = 'myai';
+  readonly displayName = 'MyAI CLI';
+
+  detectBinary(): TargetBinaryInfo | null {
+    const path = which.sync('myai', { nothrow: true });
+    if (!path) return null;
+    return { path, needsShell: process.platform === 'win32' };
+  }
+
+  async prepareCredentials(creds: TargetCredentials): Promise<void> {
+    // Write to ~/.myai/config or similar
+  }
+
+  buildArgs(profile: string, userArgs: string[]): string[] {
+    return ['-p', profile, ...userArgs];
+  }
+
+  buildEnv(creds: TargetCredentials, _profileType: string): NodeJS.ProcessEnv {
+    return {
+      ...process.env,
+      MYAI_API_KEY: creds.apiKey,
+      MYAI_API_URL: creds.baseUrl,
+    };
+  }
+
+  exec(args: string[], env: NodeJS.ProcessEnv): void {
+    const myaiPath = this.detectBinary()?.path;
+    if (!myaiPath) {
+      console.error('[X] MyAI CLI not found');
+      process.exit(1);
+    }
+    spawn(myaiPath, args, { stdio: 'inherit', env });
+  }
+
+  supportsProfileType(profileType: string): boolean {
+    return true; // or implement specific logic
+  }
+}
+```
+
+### 2. Update Type Definition
+
+```typescript
+// src/targets/target-adapter.ts
+
+export type TargetType = 'claude' | 'droid' | 'myai';
+```
+
+### 3. Register in ccs.ts
+
+```typescript
+registerTarget(new MyAiAdapter());
+```
+
+### 4. Update Documentation
+
+- Add to [Codebase Summary](../codebase-summary.md)
+- Update Code Standards adapter examples
+- Document CLI-specific behavior
+
+---
+
+## Cross-Platform Considerations
+
+### Windows Shell Detection
+
+Both adapters check for shell-requiring binaries:
+
+```typescript
+const needsShell = isWindows && /\.(cmd|bat|ps1)$/i.test(binaryPath);
+
+if (needsShell) {
+  const cmdString = [binaryPath, ...args].map(escapeShellArg).join(' ');
+  spawn(cmdString, { shell: true, stdio: 'inherit' });
+} else {
+  spawn(binaryPath, args, { stdio: 'inherit' });
+}
+```
+
+### Environment Variable Escaping
+
+Arguments passed to shell are escaped to prevent injection:
+
+```typescript
+export function escapeShellArg(arg: string): string {
+  // Wrap in quotes and escape internal quotes
+  return `"${arg.replace(/"/g, '\\"')}"`;
+}
+```
+
+### Signal Handling
+
+Both adapters propagate signals from parent to child:
+
+```typescript
+process.on('SIGINT', () => child.kill('SIGINT'));
+process.on('SIGTERM', () => child.kill('SIGTERM'));
+```
+
+This ensures CTRL+C and graceful shutdowns work correctly.
+
+---
+
+## Testing Target Adapters
+
+### Unit Tests
+
+```typescript
+describe('ClaudeAdapter', () => {
+  it('detects Claude CLI', () => {
+    const adapter = new ClaudeAdapter();
+    const binary = adapter.detectBinary();
+    expect(binary).not.toBeNull();
+  });
+
+  it('builds env with credentials', () => {
+    const adapter = new ClaudeAdapter();
+    const env = adapter.buildEnv({
+      baseUrl: 'https://api.anthropic.com',
+      apiKey: 'sk-ant-...',
+      model: 'claude-opus-4-6',
+    }, 'clipproxy');
+
+    expect(env['ANTHROPIC_AUTH_TOKEN']).toBe('sk-ant-...');
+  });
+});
+```
+
+### Integration Tests
+
+```bash
+# Test Claude adapter
+ccs --target claude help
+
+# Test Droid adapter (if installed)
+ccs --target droid help
+
+# Test argv[0] detection
+ccsd help
+```

Subject: [PATCH 323/658] fix(targets): harden edge cases from parallel code
 review

- droid-config-manager.ts: Profile name validation, backup file perms
  (0o600), symlink detection before write
- droid-detector.ts: Directory check for CCS_DROID_PATH via isFile()
- ccs.ts: Replace hardcoded guards with supportsProfileType() calls,
  add prepareCredentials to default branch
- droid-adapter.ts: errno-aware error messages (EACCES vs ENOENT)
- maintainability-baseline.json: Updated edge case metrics

Hardening fixes address permission handling, symlink detection, and
error classification for improved robustness in edge cases.

Subject: [PATCH 329/658] fix(targets): DRY signal handling, remove redundant
 guards, harden config manager

- Extract signal forwarding to reusable src/utils/signal-forwarder.ts
- Update shell-executor, claude-adapter, droid-adapter to use shared utility
- Remove 35 lines of redundant duplicate guards in src/ccs.ts
- Harden droid-config-manager with lock constants and race-safe ensureFactoryDir
- Update help-command with --target usage examples
- Update maintainability metrics baseline

Subject: [PATCH 335/658] refactor(cliproxy): DRY provider lists into single
 source of truth

- unify CLIPROXY_SUPPORTED_PROVIDERS to import from CLIPROXY_PROVIDER_IDS
- replace 4 inline union types with CLIProxyProvider import
- replace hardcoded provider arrays in migration-manager and proxy-routes
- remove duplicate PROVIDER_DISPLAY_NAMES, use getProviderDisplayName()
- sync test now imports from ui/src/lib/provider-config instead of hardcoded array

Adding a new CLIProxy provider no longer requires updating 14+ hardcoded lists.

Subject: [PATCH 336/658] feat(cliproxy): add Kimi as OAuth CLIProxy provider

- add 'kimi' to CLIProxyProvider union type
- register Kimi capabilities (device_code flow, moonshot alias)
- add OAuth config, auth prefixes, type values, channel maps
- add CLIProxy-delegated token refresh for Kimi
- add Kimi model catalog (k2.5, k2-thinking, k2)
- switch base-kimi.settings.json to CLIProxy mode (127.0.0.1:8317)
- update comments removing kimi from settings-based profile mentions

Closes #574

Subject: [PATCH 347/658] fix(core): prevent GLMT proxy leaks in child
 lifecycle

- reuse shared wireChildProcessSignals for GLMT Claude execution

- centralize proxy stop logic on child error and exit paths

- guard global signal cleanup so cleanup failures do not block exit

Subject: [PATCH 353/658] refactor(cliproxy): centralize provider auth
 capability metadata

- move callback/auth-url names, token type values, and prefixes

- derive auth maps from capabilities instead of hardcoded records

- route refresh delegation through capability ownership metadata

Subject: [PATCH 364/658] fix(cliproxy): harden provider alias and refresh edge
 cases

- guard provider alias generation against ambiguous collisions

- add account-scoped Gemini token refresh with strict account checks

- warn and fallback on invalid management remote ports

- align remaining HTTP remote defaults and extend cliproxy tests

Subject: [PATCH 365/658] fix(ui): harden cliproxy panel and proxy edge
 handling

- make iframe auto-login/reload flow race-safe and lint-compliant

- normalize API base joins and replace conflict sentinels with typed errors

- tighten proxy port validation and defer cursor preset apply until models load

- add ui api-client unit coverage for path and conflict helpers

Subject: [PATCH 371/658] fix(cliproxy): add Kimi model catalog, sync, and
 pricing to dashboard

- Add kimi entry to UI model-catalogs.ts with K2.5, K2 Thinking, K2
  models and preset mappings so dashboard shows available models
- Add kimi to CHANNEL_TO_PROVIDER and SYNCABLE_PROVIDERS in
  catalog-cache.ts so models sync from upstream CLIProxyAPI
- Add kimi/moonshot to provider-editor ownerMap for model filtering
- Update Kimi model pricing to match official Kimi Platform rates:
  kimi-k2.5 ($0.60/$3.00), kimi-k2-thinking ($0.60/$2.50),
  kimi-k2-turbo-preview ($1.15/$8.00)
- Add missing kimi-k2.5 pricing entry

Closes #581

Subject: [PATCH 372/658] fix(cliproxy): add kimi-k2 pricing and kimi catalog
 tests

Address review feedback from PR #585:
- Add missing kimi-k2 pricing entry ($0.60/$2.50, cache $0.15)
  to avoid fallback to unknown model pricing
- Add kimi provider tests to model-catalog.test.js verifying
  catalog structure, default model, and model IDs

Subject: [PATCH 376/658] feat(thinking): complete thinking UX/DX for all
 providers

- Fix codex off-mode bug: add disableEffort to CodexReasoningProxy
  so mode=off actually skips reasoning injection
- Add CCS_THINKING env var (priority: flag > env > config)
- Add startup feedback: [i] Thinking: <level> (<source>)
- Add ccs config thinking CLI subcommand with --mode, --override,
  --tier, --provider-override, --clear-override
- Dashboard: add manual override selector when mode=manual
- Dashboard: add provider overrides collapsible section
- Dashboard: update info box with CCS_THINKING env var docs
- Update help-command.ts with CCS_THINKING and config thinking

Closes #583

Subject: [PATCH 384/658] fix(delegation): strip CLAUDECODE env var to bypass
 nested session guard

Claude Code v2.1.39+ sets CLAUDECODE env var and refuses to launch
if detected, breaking CCS auto-delegation which spawns child Claude
processes. Strip the var from both interactive (execClaude) and
headless (HeadlessExecutor) spawn paths.

Closes #588

Subject: [PATCH 400/658] fix(test): scope child_process mock to test lifecycle

- register child_process module mock in beforeAll instead of module load

- keep passthrough for non-Claude commands and restore after suite

- avoids cross-suite side effects that stalled cursor daemon CI tests

Subject: [PATCH 455/658] fix(agy): align responsibility flow with issue #509

- replace issue #622/#619 references with issue #509 across CLI and dashboard

- shorten acknowledgement phrase to "I ACCEPT AGY RISK" for faster typing

- rename acknowledgement payload field to reviewedIssue509 and update tests

Subject: [PATCH 456/658] fix(auth): harden agy safety endpoints and config
 writes

- add safer error responses for settings/auth routes to avoid leaking internals

- guard sensitive AGY settings endpoints to localhost when dashboard auth is off

- validate start-route bodies and reject OAuth start in remote mode for consistency

- preserve cliproxy.kiro_no_incognito and token_refresh during config merges

- enforce AGY acknowledgement in remote auth-token run/auth command paths

Subject: [PATCH 457/658] fix(ui): improve agy auth UX and flow resilience

- re-sync AGY bypass state when backend requires risk acknowledgement

- harden auth flow response parsing for non-JSON error payloads

- prevent save collisions in Auth settings and add switch accessibility labels

- disable risky concurrent actions and add guarded refresh behavior

Subject: [PATCH 458/658] fix(ui): move agy power-user mode to proxy settings

- move Antigravity power-user toggle from Settings > Auth to Settings > Proxy

- keep Add Account messaging consistent with the new location

- retain issue #509 risk framing for AGY flows

Subject: [PATCH 459/658] fix(ui): unify gemini and agy safety warning banner

- collapse provider-specific warning variants into one shared card

- keep issue #509 as the single risk reference for both flows

- reuse cliproxy warning card space for Settings > Proxy pointer

Subject: [PATCH 461/658] fix(proxy): harden AGY risk persistence and confirm
 UX

- add lock-held mutateUnifiedConfig read-modify-write path for config.yaml

- use atomic mutation in /api/settings/auth/antigravity-risk to prevent stale overwrites

- replace browser confirm with in-app 2-step banner + typed phrase validation

- verify saved AGY power-user value with post-save read before showing success

+Need continuity between two accounts for the same project? Opt in to shared context:
+
+```bash
+# Share context with default group
+ccs auth create backup --share-context
+
+# Or isolate by named group (only accounts in this group share context)
+ccs auth create backup2 --context-group sprint-a
+```
+
+Isolation remains the default. Shared context only links project workspace data; credentials stay per-account.

 Need additional alias names? Set `CCS_DROID_ALIASES` as a comma-separated list (for example: `CCS_DROID_ALIASES=ccs-droid,mydroid`).
 
+### Per-Profile Target Defaults
+
+You can pin a default target (`claude` or `droid`) per profile:
+
+```bash
+# API profile defaults to Droid
+ccs api create myglm --preset glm --target droid
+
+# CLIProxy variant defaults to Droid
+ccs cliproxy create mycodex --provider codex --target droid
+```
+
+Built-in CLIProxy providers also work with Droid alias/target override:
+
+```bash
+ccsd codex
+ccsd agy
+ccs codex --target droid
+```
+
+Dashboard parity:
+- `ccs config` -> `API Profiles` -> set **Default Target**
+- `ccs config` -> `CLIProxy` -> create/edit variant -> set **Default Target**
+
 ### Kiro Auth Methods
 
 `ccs kiro --auth` defaults to AWS Builder ID Device OAuth (best support for AWS org accounts).

+For Factory BYOK compatibility, CCS also stores a per-profile Droid provider hint

Subject: [PATCH 504/658] fix(droid): avoid interactive model arg prompt
 pollution

- persist selector in ~/.factory/settings.json as settings.model

- stop injecting '-m custom:...' for interactive droid launches

- improve provider inference for localhost /v1 and qwen/deepseek/kimi

- add regression tests for adapter, provider, and config manager

Subject: [PATCH 507/658] fix(dashboard): align droid config diagnostics with
 factory paths

- replace ~/.config/factory/config.json diagnostics with legacy ~/.factory/config.json

- keep ~/.factory/settings.json as the primary BYOK source in UI + API payload

- update droid dashboard tests and frontend typings for legacyConfig

Subject: [PATCH 510/658] feat(dashboard): enrich droid docs and quick settings
 controls

- add reusable compatible-CLI docs registry with external provider fact-check links

- render docs links in Droid notes panel and keep future CLI extension points

- add left-column quick controls for key settings.json fields (reasoning/autonomy/diff/automation)

+# Session Sharing Technical Analysis
+
+Last Updated: 2026-02-26
+
+## Summary
+
+CCS supports practical cross-account continuity by sharing workspace context files between selected accounts, while keeping credentials isolated per account.
+
+This is implemented as a context policy per account:
+
+- `isolated` (default): account keeps its own workspace context
+- `shared`: account workspace context is linked to a shared context group
+
+## Why This Is Safe Enough
+
+CCS only shares workspace context paths (project/session context files). It does **not** merge or copy authentication credentials between accounts.
+
+Credential storage remains per account instance.
+
+## Implementation Model
+
+Account metadata is stored in `~/.ccs/config.yaml`:
+
+```yaml
+accounts:
+  work:
+    created: "2026-02-24T00:00:00.000Z"
+    last_used: null
+    context_mode: "shared"
+    context_group: "team-alpha"
+```
+
+Rules:
+
+- `context_mode` must be `isolated` or `shared`
+- `context_group` is required when `context_mode=shared`
+- group normalization: trim, lowercase, internal spaces -> `-`
+- group must start with a letter and only include `[a-zA-Z0-9_-]`
+- max length: `64`
+
+## User Workflows
+
+### New account with shared context
+
+```bash
+ccs auth create work2 --share-context
+ccs auth create backup --context-group sprint-a
+```
+
+### Existing account
+
+- Open `ccs config`
+- Go to `Accounts`
+- Click the pencil icon (`Edit Context`)
+- Choose `isolated` or `shared` and set group
+
+No account recreation required for this workflow.
+
+## Current Limitations
+
+- Shared context is local filesystem sharing. It does not bypass remote provider permission models.
+- Session continuity still depends on what the upstream tool/provider stores and allows.
+- Context sharing should only be enabled for accounts you intentionally trust to share workspace history.
+
+## Validation Checklist
+
+- Confirm account row shows `shared (<group>)` in Dashboard Accounts table
+- Switch between accounts in the same group and verify workspace continuity
+- Run `ccs doctor` if symlink/context health looks inconsistent

 - Session continuity still depends on what the upstream tool/provider stores and allows.

 - Confirm account row shows `shared (<group>)` in Dashboard Accounts table
 - Switch between accounts in the same group and verify workspace continuity
 - Run `ccs doctor` if symlink/context health looks inconsistent

@@ -172,11 +172,15 @@ CCS supports structural Droid command passthrough after profile selection:
 ```bash
 ccsd codex exec --skip-permissions-unsafe "fix failing tests"
 ccsd codex --skip-permissions-unsafe "fix failing tests"   # auto-routed to: droid exec ...
+ccsd codex -m custom:gpt-5.3-codex "fix failing tests"     # short exec flags auto-routed too
 ```
 
 If you pass exec-only flags without a prompt (for example `--skip-permissions-unsafe`),
 Droid `exec` will return its native "No prompt provided" usage guidance.
 
+If multiple reasoning flags are provided in Droid exec mode, CCS keeps the first
+flag and warns about duplicates.

Subject: [PATCH 564/658] feat(analytics): integrate CLIProxy multi-provider
 usage into dashboard

Add unified analytics tracking for all CLIProxy-routed providers
(Gemini/Droid, Codex, OpenCode, Antigravity, Qwen) alongside
existing Claude JSONL data.

- New transformer converts CLIProxy usage API response to
  DailyUsage/HourlyUsage/MonthlyUsage types
- New syncer periodically fetches CLIProxy data (5min interval)
  and persists snapshots to ~/.ccs/cache/cliproxy-usage/
- Aggregator treats CLIProxy as 3rd data source alongside
  default Claude config and CCS instances
- Charts automatically show multi-provider data in unified view
- Graceful degradation when CLIProxy is unavailable

+# Dashboard i18n Guide
+
+Last Updated: 2026-03-02
+
+This document describes the internationalization (i18n) architecture used by the CCS Dashboard (`ui/`), how locale selection works, and how to add new languages safely.
+
+---
+
+## Scope
+
+Dashboard i18n currently covers UI text rendered by React components.
+
+- Supported locales today:
+  - `en` (English)
+  - `zh-CN` (Simplified Chinese)
+- Locale state is persisted in browser localStorage using `ccs-ui-locale`.
+- Fallback language is `en`.
+
+Out of scope:
+
+- CLI terminal output localization
+- Backend/API payload localization
+
+---
+
+## Architecture
+
+### Initialization
+
+- File: `ui/src/App.tsx`
+- `import '@/lib/i18n'` initializes i18next once before routes render.
+
+### Translation resources
+
+- File: `ui/src/lib/i18n.ts`
+- Contains `resources` object with locale blocks:
+  - `en.translation`
+  - `zh-CN.translation`
+- Uses `initReactI18next` for React integration.
+
+### Locale utilities
+
+- File: `ui/src/lib/locales.ts`
+- Core helpers:
+  - `normalizeLocale(locale)` maps browser/storage values to supported app locales.
+  - `getInitialLocale` chooses stored locale, then browser locale, then `en`.
+  - `persistLocale` writes normalized locale to localStorage.
+
+### Language switcher
+
+- File: `ui/src/components/layout/language-switcher.tsx`
+- Uses `react-i18next` + shadcn `Select`.
+- Calls `persistLocale` and `i18n.changeLanguage` on selection.
+
+---
+
+## Key Conventions
+
+### Translation key naming
+
+Use dot-notation namespaces by feature area:
+
+- `nav.home`
+- `cursorPage.title`
+- `settingsTabs.web`
+
+Keep key names stable and semantic to minimize churn across locales.
+
+### Pluralization
+
+For count-based strings, use i18next suffix rules:
+
+- `<key>_one`
+- `<key>_other`
+
+Examples exist in sync/account counters.
+
+### Interpolation and rich text
+
+- Use interpolation for runtime values: `t('key', { value })`.
+- Prefer plain text keys whenever possible.
+- If formatting is required (for example bold segments), use `<Trans />` instead of `dangerouslySetInnerHTML`.
+
+---
+
+## Adding a New Locale
+
+When adding a locale such as Vietnamese (`vi`):
+
+1. Add locale id to the supported locale list in `ui/src/lib/locales.ts`.
+2. Add locale display label under `translation.locale` in `ui/src/lib/i18n.ts`.
+3. Add a full `<locale>.translation` block with all keys.
+4. Verify fallback behavior remains `en` for missing keys.
+5. Run UI validation and i18n tests:
+   - `cd ui && bun run validate`
+   - `cd ui && bun run test:run tests/unit/ui/i18n/language-switcher.test.tsx`
+6. Add or update key-parity tests to catch locale drift.
+
+Tracking issue for comprehensive Vietnamese locale:
+
+- https://github.com/kaitranntt/ccs/issues/659
+
+---
+
+## Contributor Checklist
+
+Before opening a PR that touches i18n:
+
+- [ ] New UI strings are translated in all supported locales.
+- [ ] No raw key literals appear in UI at runtime.
+- [ ] No unsafe HTML injection path introduced for translated content.
+- [ ] `ui` validate/test commands pass.
+- [ ] This document is updated if architecture or conventions changed.

-Currently, two official plugins are available:
+This UI is served by the CCS web server and is accessed via:
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh

-## React Compiler
-
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+```bash
+ccs config
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+---
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
+## Development
 
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+From project root:
+
+```bash
+bun run dev
 ```
+
+This starts the CCS server and serves the dashboard at `http://localhost:3000`.
+
+From `ui/` only (frontend dev server):
+
+```bash
+cd ui
+bun run dev
+```
+
+---
+
+## Quality Commands
+
+```bash
+cd ui
+bun run typecheck
+bun run lint
+bun run validate
+bun run test:run
+```
+
+---
+
+## i18n
+
+Dashboard localization uses `react-i18next`.
+
+- Main setup: `ui/src/lib/i18n.ts`
+- Locale helpers: `ui/src/lib/locales.ts`
+- Language switcher: `ui/src/components/layout/language-switcher.tsx`
+
+For full architecture, conventions, and locale onboarding, see:
+
+- [`../docs/i18n-dashboard.md`](../docs/i18n-dashboard.md)
+
+---
+
+## Notes
+
+- UI locale persistence uses browser localStorage key `ccs-ui-locale`.
+- Current supported locales are managed in `ui/src/lib/locales.ts`.
+- Fallback locale is English (`en`).

+#### Cross-Profile Continuity Inheritance (Claude Target)

+You can map non-account profiles (API, CLIProxy, Copilot, or `default`) to reuse continuity artifacts from an account profile:
+
+```yaml
+continuity:
+  inherit_from_account:
+    glm: pro
+    gemini: pro
+    copilot: pro

+
+With this config, `ccs glm`, `ccs gemini`, and `ccs copilot` run with `pro`'s `CLAUDE_CONFIG_DIR` continuity context while keeping each profile's own provider credentials/settings.
+
 Alternative path for lower manual switching:
 
 - Use CLIProxy Claude pool (`ccs cliproxy auth claude`) and manage pool behavior in `ccs config` -> `CLIProxy Plus`.

Subject: [PATCH 585/658] fix(usage): coalesce refresh and force live sync on
 refresh

- share one full-refresh promise across usage loaders to avoid duplicate work

- sync CLIProxy snapshot before source refresh and start sync lazily

- make refresh handler execute full refresh with proper error response

- reset pending cache state and guard sync interval double-start

Subject: [PATCH 601/658] fix(security): harden API endpoints and resolve PR
 #674 review findings

- Fix X-Forwarded-For header spoofing in requireSensitiveLocalAccess (use socket-level address only)
- Add model ID length validation (max 256 chars) in PUT /models/:provider
- Add provider name validation (alphanumeric, max 64 chars) to prevent path traversal
- Add stale entry eviction for unbounded quotaRateLimits Map (>1000 entries)
- Fix concurrent refresh race in usage aggregator (wait for in-flight before forced refresh)
- Sanitize internal URLs/paths from OAuth failure diagnostics
- Add ValidationError class for denylist violations (distinct from system errors)
- Make CLIProxy sync interval configurable via CCS_CLIPROXY_SYNC_INTERVAL env var
- Improve legacy continuity config error logging (unconditional warn)
- Add CACHE_VERSION history comments

Subject: [PATCH 602/658] refactor(routes): resolve DRY violations, config
 race, and error leaks

- Extract generic shouldCacheQuotaResult replacing 4 identical functions
- Move parseTarget to route-helpers.ts (was duplicated in profile/variant routes)
- Add createRouteErrorHelpers factory (was duplicated in auth/settings routes)
- Fix config read-then-write race in proxy-routes.ts and misc-routes.ts
  using mutateUnifiedConfig for atomic read-modify-write
- Replace raw error messages in 500 responses with generic messages +
  server-side logging across all cliproxy-stats-routes handlers
- Convert extractErrorLogMetadata from sync fs to async fs.promises

Subject: [PATCH 618/658] fix(hooks): handle thinking blocks in image analyzer
 response parsing

When models have thinking enabled (e.g. codex with thinking: auto), the
API returns content as [{ type: 'thinking', thinking: '...' }, { type:
'text', text: '...' }]. The hook reads content[0].text which is
undefined for thinking blocks, causing 'No text content in response'
errors that block the Read tool (exit 2).

Also fix cross-provider model fallback: getModelsToTry() unconditionally
appends DEFAULT_MODEL (gemini-2.5-flash) as retry, which 502s on
non-gemini provider routes (e.g. codex). Only use DEFAULT_MODEL when no
provider-specific model is configured.

Fixes: content[0].text -> content.find(b => b.type === 'text')
Fixes: cross-provider retry causing 'unknown provider' 502
Ref: #511

Subject: [PATCH 628/658] feat(auth): add --bare flag and MCP server sync for
 profiles

- Add --bare flag to `ccs auth create` to skip shared symlinks
  (commands/, skills/, agents/, settings.json). Bare profiles are
  clean instances without ClaudeKit or other global extensions.
  `ccs sync` respects bare flag and skips re-linking.

- Add MCP server sync from global ~/.claude.json to instances.
  Claude Code stores MCP config in ~/.claude.json (not settings.json),
  which was invisible to CCS profiles using CLAUDE_CONFIG_DIR isolation.
  Selective copy of mcpServers key only (not OAuth sessions/caches).
  `ccs sync` refreshes MCP servers across all non-bare instances.

Closes #691
Closes #692

Subject: [PATCH 656/658] fix(config): use correct codex haiku model ID
 (gpt-5-codex-mini)

ANTHROPIC_DEFAULT_HAIKU_MODEL in base-codex.settings.json is set to
gpt-5-mini which is not routable on the codex CLIProxy endpoint,
causing 502 'unknown provider for model gpt-5-mini' when Claude Code
spawns subagents at the haiku tier.

The correct model ID is gpt-5-codex-mini (confirmed via /v1/models).

Ref: #602
